“Write a five-paragraph essay on Virginia Woolf’s ‘To the Lighthouse.’” Too generic? Well, how about “Write a five-paragraph essay on the theme of loss in ‘To the Lighthouse’”? Too high-schoolish? “Add some bigger words, please.” The product might not be ready to turn in the moment it is born, fully formed, from ChatGPT’s head. But with enough tweaking — either by the student or by the machine at the student’s demand — chances are the output can muster at least a passing grade.

Which of these uses are okay? Which aren’t? The harnessing of an AI tool to create an annotated bibliography likely doesn’t rankle even librarians the way relying on that same tool to draft a reflection on Virginia Woolf offends the professor of the modern novel. Why? Because that kind of contemplation goes closer to the heart of what education is really about.

the core of the question colleges now face. They can’t really stop students from using AI in class. They might not be able to notice students have done so at all, and when they do think they’ve noticed they’ll be acting only on suspicion. But maybe teachers can control the ways in which students use AI in class.

Figuring out exactly what ways those ought to be requires educators to determine what they care about in essays — what they are desperate to hear. The purpose of these papers is for students to demonstrate what they’ve learned, from hard facts to compositional know-how, and for teachers to assess how their pupils are progressing. The answer to what teachers want to get from students in their written work depends on what they want to give to students.

What’s most important to Ole Miss faculty members is that students use these tools with integrity. If the university doesn’t have a campuswide AI honor code, and so far it doesn’t, individual classes should. And no matter whether professors permit all applications of AI, as some teachers have tried, or only the narrowest, students should have to disclose just how much help they had from robots.

The next concern is that students should use AI in a manner that improves not only their writing but also their thinking — in short, in a manner that enhances learning rather than bypasses the need to learn at all.

This simple principle makes for complicated practice. Certainly, no one is going to learn anything by letting AI write an essay in its entirety. What about letting AI brainstorm an idea, on the other hand, or write an outline, or gin up a counter-argument? Lyndsey Cook, a senior at Ole Miss planning a career in nursing, finds the brainstorming especially helpful: She’ll ask ChatGPT or another tool to identify the themes in a piece of literature, and then she’ll go back and look for them herself.

These shortcuts, on the one hand, might interfere with students’ learning to brainstorm, outline or see the other side of things on their own

But — here comes a human-generated counterargument — they may also aid students in surmounting obstacles in their composition that otherwise would have stopped them short. That’s particularly true of kids whose high schools didn’t send them to college already equipped with these capabilities.

Allow AI to boost you over these early hurdles, and suddenly the opportunity for deeper learning — the opportunity to really write — will open up. That’s how Caleb Jackson, the part-time student for whom Perplexity has been such a boon, sees it: His professor, he says , wanted them to “get away from the high-school paper and go further, to write something larger like a thesis.”

maybe, as one young Ole Miss faculty member put it to me, this risks “losing the value of the struggle.” That, she says, is what she is scared will go away.

All this invites the most important question there is: What is learning for?

Learning, in college, can be instrumental. According to this view, the aim of teaching is to prepare students to live in the real world, so all that really matters is whether they have the chops to field jobs that feed themselves and their families. Perhaps knowing how to use AI to do any given task for you, then, is one of the most valuable skills out there — the same way it pays to be quick with a calculator.

If you accept this line of argument, however, there are still drawbacks to robotic crutches. Some level of critical thinking is necessary to function as an adult, and if AI stymies its development even the instrumental aim of education is thwarted. The same goes for that “value of the struggle.” The real world is full of adversity, much of which the largest language model can’t tell you how to overcome.

more compelling is the idea, probably shared by most college professors, that learning isn’t only instrumental after all — that it has intrinsic value and that it is the end rather than merely a means to one.

Every step along the way that is skipped, the shorter the journey becomes, the less we will take in as we travel.

This glummest of outlooks suggests that AI will stunt personal growth even if it doesn’t harm professional prospects.

While that doesn’t mean it’s wise to prohibit every little application of the technology in class, it probably does mean discouraging those most closely related to critical thinking.

One approach is to alter standards for grading, so that the things the machines are worst at are also the things that earn the best marks: originality, say, or depth of feeling, or so-called metacognition — the process of thinking about one’s own thinking or one’s own learning.

Hopefully, these things are also the most valuable because they are what make us human.

Caleb Jackson only wants AI to help him write his papers — not to write them for him. “If ChatGPT will get you an A, and you yourself might get a C, it’s like, ‘Well, I earned that C.’” He pauses. “That might sound crazy.”

Dominic Tovar agrees. Let AI take charge of everything, and, “They’re not so much tools at that point. They’re just replacing you.”

Lyndsey Cook, too, believes that even if these systems could reliably find the answers to the most vexing research problems, “it would take away from research itself” — because scientific inquiry is valuable for its own sake. “To have AI say, ‘Hey, this is the answer …’” she trails off, sounding dispirited.

Claire Mischker, lecturer of composition and director of the Ole Miss graduate writing center, asked her students at the end of last semester to turn in short reflections on their experience in her class. She received submissions that she was near certain were produced by ChatGPT — “that,” she says as sarcastically as she does mournfully, “felt really good.

The central theme of the course was empathy.

While sex is a category that refers broadly to physiology, a person's gender is an innate sense of identity. The factors that go into determining the sex listed on a birth certificate may include anatomy, genetics and hormones, and there is broad natural variation in each of these categories. For this reason, critics have said the language of "biological sex," as used in DeSantis' proclamation, is overly simplistic and misleading.A 2017 report in the journal Sports Medicine that reviewed several related studies found "no direct or consistent research" on trans people having an athletic advantage over their cisgender peers, at any state of their transition, and critics say postures like DeSantis' will only add to the discrimination that trans people face, particularly trans youth.

So far this year, Iowa and South Dakota have approved legislation banning transgender women and girls from participating on sports teams consistent with their gender at accredited schools and colleges. And last year, Alabama, Arkansas, Florida, Mississippi, Montana, Tennessee, Texas and West Virginia enacted similar sports bans, infuriating LGBTQ advocates, who argue conservatives are creating an issue where there isn't one.

titled “Tightness-Looseness Across the 50 United States,” the study calculated a catalog of measures for each state, including the incidence of natural disasters, disease prevalence, residents’ levels of openness and conscientiousness, drug and alcohol use, homelessness and incarceration rates.

Gelfand said:Some groups have much stronger norms than others; they’re tight. Others have much weaker norms; they’re loose. Of course, all cultures have areas in which they are tight and loose — but cultures vary in the degree to which they emphasize norms and compliance with them.

states in New England and on the West Coast were the loosest: California, Oregon, Washington, Maine, Massachusetts, Connecticut, New Hampshire and Vermont.

In both 2016 and 2020, Donald Trump carried all 10 of the top “tight” states; Hillary Clinton and Joe Biden carried all 10 of the top “loose” states.

“Rule Makers, Rule Breakers: How Tight and Loose Cultures Wire the World” in 2018, in which she described the results of a 2016 pre-election survey she and two colleagues had commissioned

The results were telling: People who felt the country was facing greater threats desired greater tightness. This desire, in turn, correctly predicted their support for Trump. In fact, desired tightness predicted support for Trump far better than other measures. For example, a desire for tightness predicted a vote for Trump with 44 times more accuracy than other popular measures of authoritarianism.

The 2016 election, Gelfand continued, “turned largely on primal cultural reflexes — ones that had been conditioned not only by cultural forces, but by a candidate who was able to exploit them.”

Along the same lines, if liberals and conservatives hold differing moral visions, not just about what makes a good government but about what makes a good life, what turned the relationship between left and right from competitive to mutually destructive?

Cultural differences, Gelfand continued, “have a certain logic — a rationale that makes good sense,” noting that “cultures that have threats need rules to coordinate to survive (think about how incredibly coordinated Japan is in response to natural disasters).

cultures that don’t have a lot of threat can afford to be more permissive and loose.”

The tight-loose concept, Gelfand argued,is an important framework to understand the rise of President Donald Trump and other leaders in Poland, Hungary, Italy, and France,

The gist is this: when people perceive threat — whether real or imagined, they want strong rules and autocratic leaders to help them survive

My research has found that within minutes of exposing study participants to false information about terrorist incidents, overpopulation, pathogen outbreaks and natural disasters, their minds tightened. They wanted stronger rules and punishments.

The South dominated the tight states: Mississippi, Alabama Arkansas, Oklahoma, Tennessee, Texas, Louisiana, Kentucky, South Carolina and North Carolina

Looseness, Gelfand posits, fosters tolerance, creativity and adaptability, along with such liabilities as social disorder, a lack of coordination and impulsive behavior.

If liberalism and conservatism have historically played a complementary role, each checking the other to constrain extremism, why are the left and right so destructively hostile to each other now, and why is the contemporary political system so polarized?

Gelfand writes that tightness encourages conscientiousness, social order and self-control on the plus side, along with close-mindedness, conventional thinking and cultural inertia on the minus side.

Niemi contended that sensitivity to various types of threat is a key factor in driving differences between the far left and far right.

She cited research thatfound 47 percent of the most extreme conservatives strongly endorsed the view that “The world is becoming a more and more dangerous place,” compared to 19 percent of the most extreme liberals

Conservatives and liberals, Niemi continued,see different things as threats — the nature of the threat and how it happens to stir one’s moral values (and their associated emotions) is a better clue to why liberals and conservatives react differently.

Unlike liberals, conservatives strongly endorse the binding moral values aimed at protecting groups and relationships. They judge transgressions involving personal and national betrayal, disobedience to authority, and disgusting or impure acts such as sexually or spiritually unchaste behavior as morally relevant and wrong.

Underlying these differences are competing sets of liberal and conservative moral priorities, with liberals placing more stress than conservatives on caring, kindness, fairness and rights — known among scholars as “individualizing values

conservatives focus more on loyalty, hierarchy, deference to authority, sanctity and a higher standard of disgust, known as “binding values.”

As a set, Niemi wrote, conservative binding values encompassthe values oriented around group preservation, are associated with judgments, decisions, and interpersonal orientations that sacrifice the welfare of individuals

Just as ecological factors differing from region to region over the globe produced different cultural values, ecological factors differed throughout the U.S. historically and today, producing our regional and state-level dimensions of culture and political patterns.

Niemi cited a paper she and Liane Young, a professor of psychology at Boston College, published in 2016, “When and Why We See Victims as Responsible: The Impact of Ideology on Attitudes Toward Victims,” which tested responses of men and women to descriptions of crimes including sexual assaults and robberies.

We measured moral values associated with unconditionally prohibiting harm (“individualizing values”) versus moral values associated with prohibiting behavior that destabilizes groups and relationships (“binding values”: loyalty, obedience to authority, and purity)

Increased endorsement of binding values predicted increased ratings of victims as contaminated, increased blame and responsibility attributed to victims, increased perceptions of victims’ (versus perpetrators’) behaviors as contributing to the outcome, and decreased focus on perpetrators.

For example, binding values are associated with Machiavellianism (e.g., status-seeking and lying, getting ahead by any means, 2013); victim derogation, blame, and beliefs that victims were causal contributors for a variety of harmful acts (2016, 2020); and a tendency to excuse transgressions of ingroup members with attributions to the situation rather than the person (2023).

What happened to people ecologically affected social-political developments, including the content of the rules people made and how they enforced them

Numerous factors potentially influence the evolution of liberalism and conservatism and other social-cultural differences, including geography, topography, catastrophic events, and subsistence styles

Joshua Hartshorne, who is also a professor of psychology at Boston College, took issue with the binding versus individualizing values theory as an explanation for the tendency of conservatives to blame victims:

I would guess that the reason conservatives are more likely to blame the victim has less to do with binding values and more to do with the just-world bias (the belief that good things happen to good people and bad things happen to bad people, therefore if a bad thing happened to you, you must be a bad person).

Belief in a just world, Hartshorne argued, is crucial for those seeking to protect the status quo:It seems psychologically necessary for anyone who wants to advocate for keeping things the way they are that the haves should keep on having, and the have-nots have got as much as they deserve. I don’t see how you could advocate for such a position while simultaneously viewing yourself as moral (and almost everyone believes that they themselves are moral) without also believing in the just world

Conversely, if you generally believe the world is not just, and you view yourself as a moral person, then you are likely to feel like you have an obligation to change things.

I asked Lene Aaroe, a political scientist at Aarhus University in Denmark, why the contemporary American political system is as polarized as it is now, given that the liberal-conservative schism is longstanding. What has happened to produce such intense hostility between left and right?

There is variation across countries in hostility between left and right. The United States is a particularly polarized case which calls for a contextual explanatio

A central explanation typically offered for the current situation in American politics is that partisanship and political ideology have developed into strong social identities where the mass public is increasingly sorted — along social, partisan, and ideological lines.

I then asked Aaroe why surveys find that conservatives are happier than liberals. “Some research,” she replied, “suggests that experiences of inequality constitute a larger psychological burden to liberals because it is more difficult for liberals to rationalize inequality as a phenomenon with positive consequences.”

Steven Pinker, a professor of psychology at Harvard, elaborated in an email on the link between conservatism and happiness:

t’s a combination of factors. Conservatives are likelier to be married, patriotic, and religious, all of which make people happier

They may be less aggrieved by the status quo, whereas liberals take on society’s problems as part of their own personal burdens. Liberals also place politics closer to their identity and striving for meaning and purpose, which is a recipe for frustration.

Some features of the woke faction of liberalism may make people unhappier: as Jon Haidt and Greg Lukianoff have suggested, wokeism is Cognitive Behavioral Therapy in reverse, urging upon people maladaptive mental habits such as catastrophizing, feeling like a victim of forces beyond one’s control, prioritizing emotions of hurt and anger over rational analysis, and dividing the world into allies and villains.

Why, I asked Pinker, would liberals and conservatives react differently — often very differently — to messages that highlight threat?

It may be liberals (or at least the social-justice wing) who are more sensitive to threats, such as white supremacy, climate change, and patriarchy; who may be likelier to moralize, seeing racism and transphobia in messages that others perceive as neutral; and being likelier to surrender to emotions like “harm” and “hurt.”

The authors used neural imaging to follow changes in the dorsomedial prefrontal cortex (known as DMPFC) as conservatives and liberals watched videos presenting strong positions, left and right, on immigration.

there are ways to persuade conservatives to support liberal initiatives and to persuade liberals to back conservative proposals:

While liberals tend to be more concerned with protecting vulnerable groups from harm and more concerned with equality and social justice than conservatives, conservatives tend to be more concerned with moral issues like group loyalty, respect for authority, purity and religious sanctity than liberals are. Because of these different moral commitments, we find that liberals and conservatives can be persuaded by quite different moral arguments

For example, we find that conservatives are more persuaded by a same-sex marriage appeal articulated in terms of group loyalty and patriotism, rather than equality and social justice.

“political arguments reframed to appeal to the moral values of those holding the opposing political position are typically more effective

We find support for these claims across six studies involving diverse political issues, including same-sex marriage, universal health care, military spending, and adopting English as the nation’s official language.”

In one test of persuadability on the right, Feinberg and Willer assigned some conservatives to read an editorial supporting universal health care as a matter of “fairness (health coverage is a basic human right)” or to read an editorial supporting health care as a matter of “purity (uninsured people means more unclean, infected, and diseased Americans).”

Conservatives who read the purity argument were much more supportive of health care than those who read the fairness case.

Liberals who read the fairness argument were substantially more supportive of military spending than those who read the loyalty and authority argument.

In “Conservative and Liberal Attitudes Drive Polarized Neural Responses to Political Content,” Willer, Yuan Chang Leong of the University of Chicago, Janice Chen of Johns Hopkins and Jamil Zaki of Stanford address the question of how partisan biases are encoded in the brain:

society. How do such biases arise in the brain? We measured the neural activity of participants watching videos related to immigration policy. Despite watching the same videos, conservative and liberal participants exhibited divergent neural responses. This “neural polarization” between groups occurred in a brain area associated with the interpretation of narrative content and intensified in response to language associated with risk, emotion, and morality. Furthermore, polarized neural responses predicted attitude change in response to the videos.

The four authors argue that their “findings suggest that biased processing in the brain drives divergent interpretations of political information and subsequent attitude polarization.” These results, they continue, “shed light on the psychological and neural underpinnings of how identical information is interpreted differently by conservatives and liberals.”

While liberals and conservatives, guided by different sets of moral values, may make agreement on specific policies difficult, that does not necessarily preclude consensus.

or each video,” they write,participants with DMPFC activity time courses more similar to that of conservative-leaning participants became more likely to support the conservative positio

Conversely, those with DMPFC activity time courses more similar to that of liberal-leaning participants became more likely to support the liberal position. These results suggest that divergent interpretations of the same information are associated with increased attitude polarizatio

Together, our findings describe a neural basis for partisan biases in processing political information and their effects on attitude change.

Describing their neuroimaging method, the authors point out that theysearched for evidence of “neural polarization” activity in the brain that diverges between people who hold liberal versus conservative political attitudes. Neural polarization was observed in the dorsomedial prefrontal cortex (DMPFC), a brain region associated with the interpretation of narrative content.

The question is whether the political polarization that we are witnessing now proves to be a core, encoded aspect of the human mind, difficult to overcome — as Leong, Chen, Zaki and Willer sugges

— or whether, with our increased knowledge of the neural basis of partisan and other biases, we will find more effective ways to manage these most dangerous of human predispositions.

Teachers are not only burnt out and undercompensated, they are also demoralized. They are being asked to do things in the name of teaching that they believe are mis-educational and harmful to students and the profession. What made this work good for them is no longer accessible. That is why we are hearing so many refrains of “I’m not leaving the profession, my profession left me.”

We find there are at least 36,000 vacant positions along with at least 163,000 positions being held by underqualified teachers, both of which are conservative estimates of the extent of teacher shortages nationally.

“The current problem of teacher shortages (I would further break this down into vacancy and under-qualification) is higher than normal.” The data, Nguyen continued, “indicate that shortages are worsening over time, particularly over the last few years

a growing gap between the pay of all college graduates and teacher salaries from 1979 to 2021, with a sharp increase in the differential since 2010

The number of qualified teachers is declining for the whole country and the vast majority of states.

Wages are essentially unchanged from 2000 to 2020 after adjusting for inflation. Teachers have about the same number of students. But, teacher accountability reforms have increased the demands on their positions.

The pandemic was very difficult for teachers. Their self-reported level of stress was about as twice as high during the pandemic compared to other working adults. Teachers had to worry both about their personal safety and deal with teaching/caring for students who are grieving lost family members.

the number of students graduating from college with bachelor’s degrees in education fell from 176,307 in 1970-71 to 104,008 in 2010-11 to 85,058 in 2019-20.

We do see that southern states (e.g., Mississippi, Alabama, Georgia and Florida) have very high vacancies and high vacancy rates.”

By 2021, teachers made $1,348, 32.9 percent less than what other graduates made, at $2,009.

These gaps play a significant role in determining the quality of teachers,

Sixty percent of teachers and 65 percent of principals reported believing that systemic racism exists. Only about 20 percent of teachers and principals reported that they believe systemic racism does not exist, and the remainder were not sure

“We find,” they write, “that teachers’ cognitive skills differ widely among nations — and that these differences matter greatly for students’ success in school. An increase of one standard deviation in teacher cognitive skills is associated with an increase of 10 to 15 percent of a standard deviation in student performance.”

teachers have lower cognitive skills, on average, in countries with greater nonteaching job opportunities for women in high-skill occupations and where teaching pays relatively less than other professions.

the scholars found that the cognitive skills of teachers in the United States fell in the middle ranks:Teachers in the United States perform worse than the average teacher sample-wide in numeracy, with a median score of 284 points out of a possible 500, compared to the sample-wide average of 292 points. In literacy, they perform slightly better than average, with a median score of 301 points compared to the sample-wide average of 295 points.

Increasing teacher numeracy skills by one standard deviation increases student performance by nearly 15 percent of a standard deviation on the PISA math test. Our estimate of the effect of increasing teacher literacy skills on students’ reading performance is slightly smaller, at 10 percent of a standard deviation.

How, then, to raise teacher skill level in the United States? Hanushek and his two colleagues have a simple answer: raise teacher pay to make it as attractive to college graduates as high-skill jobs in other fields.

policymakers will need to do more than raise teacher pay across the board to ensure positive results. They must ensure that higher salaries go to more effective teachers.

The teaching of disputed subjects in schools has compounded many of the difficulties in American education.

The researchers found that controversies over critical race theory, sex education and transgender issues — aggravated by divisive debates over responses to Covid and its aftermath — are inflicting a heavy toll on teachers and principals.

“On top of the herculean task of carrying out the essential functions of their jobs,” they write, “educators increasingly find themselves in the position of addressing contentious, politicized issues in their schools as the United States has experienced increasing political polarization.”

Teachers and principals, they add, “have been pulled in multiple directions as they try to balance and reconcile not only their own beliefs on such matters but also the beliefs of others around them, including their leaders, fellow staff, students, and students’ family members.”

These conflicting pressures take place in a climate where “emotions in response to these issues have run high within communities, resulting in the harassment of educators, bans against literature depicting diverse characters, and calls for increased parental involvement in deciding academic content.”

Forty-eight percent of principals and 40 percent of teachers reported that the intrusion of political issues and opinions in school leadership or teaching, respectively, was a job-related stressor. By comparison, only 16 percent of working adults indicated that the intrusion of political issues and opinions in their jobs was a source of job-related stress

In 1979, the average teacher weekly salary (in 2021 dollars) was $1,052, 22.9 percent less than other college graduates’, at $1,364

Nearly all Black or African American principals (92 percent) and teachers (87 percent) reported believing that systemic racism exists.

White educators working in predominantly white school systems reported substantially more pressure to deal with politically divisive issues than educators of color and those working in mostly minority schools: “Forty-one percent of white teachers and 52 percent of white teachers and principals selected the intrusion of political issues and opinions into their professions as a job-related stressor, compared with 36 percent of teachers of color and principals of color.

and opinions into their professions as a job-related stressor, compar

A 54 percent majority of teachers and principals said there “should not be legal limits on classroom conversations about racism, sexism, and other topics,” while 20 percent said there should be legislated constraint

Voters, in turn, are highly polarized on the teaching of issues impinging on race or ethnicity in public schools. The Education Next 2022 Survey asked, for example:Some people think their local public schools place too little emphasis on slavery, racism and other challenges faced by Black people in the United States. Other people think their local public schools place too much emphasis on these topics. What is your view about your local public schools?

Among Democrats, 55 percent said too little emphasis was placed on slavery, racism and other challenges faced by Black people, and 8 percent said too much.

Among Republicans, 51 said too much and 10 percent said too little.

Because of the lack of reliable national data, there is widespread disagreement among scholars of education over the scope and severity of the shortage of credentialed teachers, although there is more agreement that these problems are worse in low-income, high majority-minority school systems and in STEM and special education faculties.

Public schools increasingly are targets of conservative political groups focusing on what they term “Critical Race Theory,” as well as issues of sexuality and gender identity. These political conflicts have created a broad chilling effect that has limited opportunities for students to practice respectful dialogue on controversial topics and made it harder to address rampant misinformation.

The chilling effect also has led to marked declines in general support for teaching about race, racism, and racial and ethnic diversity.

These political conflicts, the authors wrote,have made the already hard work of public education more difficult, undermining school management, negatively impacting staff, and heightening student stress and anxiety. Several principals shared that they were reconsidering their own roles in public education in light of the rage at teachers and rage at administrators’ playing out in their communities.

State University of New York tracked trends on “four interrelated constructs: professional prestige, interest among students, preparation for entry, and job satisfaction” for 50 years, from the 1970s to the present and founda consistent and dynamic pattern across every measure: a rapid decline in the 1970s, a swift rise in the 1980s, relative stability for two decades, and a sustained drop beginning around 2010. The current state of the teaching profession is at or near its lowest levels in 50 years.

Who among the next generation of college graduates will choose to teach?

Perceptions of teacher prestige have fallen between 20 percent and 47 percent in the last decade to be at or near the lowest levels recorded over the last half century

Interest in the teaching profession among high school seniors and college freshmen has fallen 50 percent since the 1990s, and 38 percent since 2010, reaching the lowest level in the last 50 years

the proportion of college graduates that go into teaching is at a 50-year low

Teachers’ job satisfaction is also at the lowest level in five decades, with the percent of teachers who feel the stress of their job is worth it dropping from 81 percent to 42 percent in the last 15 years

The combination of these factors — declining prestige, lower pay than other professions that require a college education, increased workloads, and political and ideological pressures — is creating both intended and unintended consequences for teacher accountability reforms mandating tougher licensing rules, evaluations and skill testing.

Education policy over the past decade has focused considerable effort on improving human capital in schools through teacher accountability. These reforms, and the research upon which they drew, were based on strong assumptions about how accountability would affect who decided to become a teacher. Counter to most assumptions, our findings document how teacher accountability reduced the supply of new teacher candidates by, in part, decreasing perceived job security, satisfaction and autonomy.

The reforms, Kraft and colleagues continued, increasedthe likelihood that schools could not fill vacant teaching positions. Even more concerning, effects on unfilled vacancies were concentrated in hard-to-staff schools that often serve larger populations of low-income students and students of color

We find that evaluation reforms increased the quality of newly hired novice teachers by reducing the number of teachers that graduated from the least selective institutions

We find no evidence that evaluation reforms served to attract teachers who attended the most selective undergraduate institutions.

In other words, the economic incentives, salary structure and work-life pressures characteristic of public education employment have created a climate in which contemporary education reforms have perverse and unintended consequences that can worsen rather than alleviate the problems facing school systems.

If so, to improve the overall quality of the nation’s more than three million public schoolteachers, reformers may want to give priority to paychecks, working conditions, teacher autonomy and punishing workloads before attempting to impose higher standards, tougher evaluations and less job security.

Blend these factors — a desire for escape from our virtual lives; bidding as fast as pushing a button; and the promotion of new collecting fields like outdated technology devices — and you have Heritage Auctions in Dallas.

Heritage is a whirlwind of activity, of passion, of hype, constantly trying new ways of enticing people to own something beautiful and useless. Ninety-one million Americans, according to U.S. Census Bureau surveys, are having trouble paying household bills. Everyone else is a potential bidder.

Twenty years ago, Heritage had four categories: coins, comics, movie posters and sports. Now it has more than 50, which generated revenue of $1.4 billion last year. Everything, at least in theory, is collectible.

“We don’t question the value or legitimacy of a particular subject matter relative to outmoded norms,” Mr. Benesh said. “We’re not here to tell you what’s worthwhile. The marketplace will tell you. The bidders” — Heritage has 1.6 million — “will tell you.”

In mid-2020, the privately held company moved to a 160,000-square-foot building by Dallas-Fort Worth International Airport, doubling the size of its former headquarters. Hundreds of specialists, most of them collectors themselves, prepare hundreds of thousands of items for bids here — researching, photographing, writing catalog copy.

The problem is, older historical items that were previously unknown are becoming rare. Every barn, basement and attic has been ransacked for treasures. New items related to Washington or Lincoln, for instance, are nearly impossible to find.

With consumers buying so little, at least relative to the Chinese economy’s productive capacity, how can the nation generate enough demand to keep that capacity in use? The main answer, as Michael Pettis points out, has been to promote extremely high rates of investment, more than 40 percent of G.D.P. The trouble is that it’s hard to invest that much money without running into severely diminishing returns.

financial repression — paying low interest on savings and making cheap loans to favored borrowers — that holds down household income and diverts it to government-controlled investment, a weak social safety net that causes families to accumulate savings to deal with possible emergencies, and more.

Part of the answer is bad leadership. President Xi Jinping is starting to look like a poor economic manager, whose propensity for arbitrary interventions — which is something autocrats tend to do — has stifled private initiative.

But China’s working-age population peaked around 2010 and has been declining ever since. While China has shown impressive technological capacity in some areas, its overall productivity also appears to be stagnating.

very high rates of investment may be sustainable if, like China in the early 2000s, you have a rapidly growing work force and high productivity growth as you catch up with Western economies

This, in short, isn’t a nation that can productively invest 40 percent of G.D.P. Something has to give.

the government was able to mask the problem of inadequate consumer spending for a number of years by promoting a gigantic real estate bubble. In fact, China’s real estate sector became insanely large by international standards.

what China must do seems straightforward: end financial repression and allow more of the economy’s income to flow through to households, and strengthen the social safety net so that consumers don’t feel the need to hoard cash. And as it does this it can ramp down its unsustainable investment spending.

But there are powerful players, especially state-owned enterprises, that benefit from financial repression

And when it comes to strengthening the safety net, the leader of this supposedly communist regime sounds a bit like the governor of Mississippi, denouncing “welfarism” that creates “lazy people.”

Japan ended up managing its downshifting well. It avoided mass unemployment, it never lost social and political cohesion, and real G.D.P. per working-age adult actually rose 50 percent over the next three decades, not far short of growth in the United States.

My great concern is that China may not respond nearly as well. How cohesive will China be in the face of economic trouble? Will it try to prop up its economy with an export surge that will run headlong into Western efforts to promote green technologies? Scariest of all, will it try to distract from domestic difficulties by engaging in military adventurism?

The basic driver is this: “Europe has an aging population that values its free time and social benefits over work and productivity. (This reduces labor force participation, innovation potential, and the economic growth of the continent.)

The eurozone economy grew about 6% over the past 15 years, measured in dollars, compared with 82% for the US, according to International Monetary Fund data. That has left the average EU country poorer per head than every US state except Idaho and Mississippi

If the current trend continues, by 2035 the gap between economic output per capita in the US and EU will be as large as that between Japan and Ecuador today

even in Smith’s figures, there is no Northern European economy that outperforms the US.

The US economy has grown 82% in fifteen years! Barring anything more than a mild recession, that means that we can expect the US economy to more than double by the time we hit 20 years from 2008. Isn’t that wonderful?

It’s not just a case of doubling the overall size of the economy. The increase in wealth has been widely distributed.

I was struck by a calculation by George Washington University’s Stephen Rose that he describes at a center-left newsletter called The Liberal Patriot

Deciding what is “middle class” versus “lower middle class” versus “upper middle class” is difficult, and every analysis sets up different cutoffs between these categories. But Rose sets a reasonable level, describing “upper middle class” as an income between $100,000 and $350,000

Using this measure, there was real growth in every rung of the economic ladder over the period from 1979 to 2019, with each ascending step having slightly higher percentage gain….

In brief, economic growth from 1979 to 2019 led more of the population to move up to higher social classes. As Table 1 shows, the bottom two categories—poor and near-poor plus lower middle class—went from a combined 49 percent to 29 percent

The size of the [core middle class] also declined, down from 39 percent to 31 percent over these years

These declines manifest themselves in a massive—and massively under-covered—growth of the [upper middle class], spiking from 13 percent in 1979 to 37 percent in 2019.

America has always thought of itself as a middle-class country. But we are rapidly becoming an upper-middle-class country

This is now the largest category, and at the rate we’re going, it will soon be an outright majority.

upper-middle-class people can afford more welfare-state spending, and they also have more access to education and, frankly, the luxury of agonizing over something other than our pocketbooks. It has been a long time since most Americans were concerned about how to put a roof over our heads, so we have moved on from “kitchen table” issues to concerns about values and status and self-image.

in this context, the Old Left welfare-state programs look, not merely unnecessary, but callous and cruel

the incentives created by welfare programs discourage work for the poor. But in a growing and thriving upper-middle-class country, this looks like a way to create a permanent underclass who are kept in poverty so we can congratulate ourselves on our compassion and generosity

some of this may also explain the right’s belligerent opposition to immigration. If we are becoming an upper-middle-class country, perhaps we are taking on some of the attitudes of a gated community that wants to keep out the riff-raff.
