what can policy do to limit inequality? The answer is, it can operate on two fronts. It can engage in redistribution, taxing high incomes and aiding families with lower incomes. It can also engage in what is sometimes called “predistribution,” strengthening the bargaining power of lower-paid workers and limiting the opportunities for a handful of people to make giant sums.

We can see this in our own history. The middle-class society that baby boomers like me grew up in didn’t happen by accident; it was created by the New Deal, which engineered what economists call the “Great Compression,” a sharp reduction in income gaps.

Obamacare provides aid and subsidies mainly to lower-income working Americans, and it pays for that aid partly with higher taxes at the top. That makes it an important redistributionist policy — the biggest such policy since the 1960s.

In truth, this conventional view relies upon imaginary facts.

Let me repeat: black elementary school students today have better math skills than white students did only twenty years ago.

children from low-income families spend more time handling technology -- across platforms -- than their wealthier counterparts, and across class, kids mainly use their "handling skills" for entertainment. They play games, watch videos, and visit social networking sites.

there's scant evidence that anyone but the companies who make, sell, and advertise on these new technologies benefit from the time young children spend with them, there's plenty of reason to be worried about it.

studies showing that the bells and whistles of electronic books actually detract from reading comprehension.

A study using Current Population Survey data shows that, from 1996 to 2012, elementary, middle, and high school teachers earned less than other college graduates, but the gap was smaller for public school teachers and smaller still if they had union representation; moreover, the mitigating effects are stronger for female than male teachers, so the within-gender pay gaps are much larger for male teachers.

Whyville , What does it take to build a sustainable, green energy community? 8th Graders are showing us how using WhyPower, an interactive learning game within the largest interactive learning world, WhyVille. Here is an interactive game. http://www.poweracrosstexas.org/projects/whypower-interactive-game Energy Game:  WHYPOWER Whyville is a thriving community with its own economy, newspaper, government and much more.  It now has its own power grid!  As part of the WhyCareers program, we are “electrifying” Whyville with a power grid that uses traditional and renewable energy sources.  Students will manage the power grid to select the right mix of coal, natural gas, nuclear, hydroelectric, solar and wind energy. They will build homes in Whyville!  They will observe and measure power use in Whyville, and form good energy behaviors and habits. Finally, they will explore the math, science and career topics related to energy.  Just like in real life, success in Whyville is not pre-programmed!  Students skill, initiative, creativity and teamwork determines the rewards they receive and the “virtual money” they earn in WhyPower. Whyville. Run a city using energy reources.

After a technology is developed, it generally takes years if not decades for management to learn how to leverage that technology to create efficiencies. Which means that the recent explosion of technology tools represents a huge untapped opportunity. A case in point: my new Droid smartphone. I have just begun to tap into the incredible stuff it can do. For example, have you ever been listening to the radio and said, 'Oh, I love this song. I wish I knew who sings it'? Well, now you can download an app for it. Your phone will listen to the song, identify it, tell you all about it and even let you buy it on the spot.
