Looking back over the past 90 years, income is now concentrated in a way that hasn’t been seen since the 1920s, she said. In the past decade, almost a third of income growth has gone to the richest 1 per cent, she added.

The big picture shows that after the Second World War, Canadian society distributed income in an increasingly level fashion. From 1946 to 1977, she writes, the income share of the richest 1 per cent fell from 14 per cent to 7.7 per cent. That trend was reversed over the past 30 years, as the top 1 per cent regained its 14-per-cent share of Canadian income. Over that time, the richest 0.1 per cent almost tripled their income share and the richest 0.01 per cent increased their share fivefold.

Median incomes, meanwhile, have been stagnant

“You’ve always had these people who’ve got their fingers on something the rest of us don’t. But why are they suddenly worth many multiples of what they were back then?” Ms. Yalnizyan said.

The answer, she said, is not economics. It’s in our culture.

Economist Michael Veall, who teaches at McMaster University, said a few theories try to explain the income shift by focusing on changes in the labour market at the high end, particularly for managers. One view is that corporate governors have allowed CEO salaries to jump because they were climbing elsewhere. Another is that CEOs, known for being superb communicators, are more effective, and thus more valuable, in the digital age because e-mail and the mass media facilitate contact with employees and the public, Prof. Veall said.

There are two reasons for hope. One is, oddly, the result of an aging population and the consequent shrinking pool of workers, which may push up wages for workers producing basic goods and services, not just those at the top of the skill spectrum. The other is a culture shift, where a growing number of boomers understand what is at play and start working with others to come up with ways to ensure there will be a resilient middle class for the next generation.

When the cost of something goes up, we tend to consume less of it. So, since living wages are higher than minimum wages, employers are likely to hire fewer workers. A living wage campaign is part of the effort to raise the visibility of a sorry development in Canada. The saying that "the best social policy is a job" is in many ways true; but a new reality has developed over the past decade or so - that you can't necessarily escape poverty by working. Working full-time full-year at a minimum wage job, as many adults do, condems you to poverty.

international statistics show that poverty rates are lowest where income inequality is lowest too. That can be because of culture -- the wage spectrum is compressed, as in Japan, where it is unseemly to get too far ahead of others in pay -- or through active redistribution programs, where taxes and the services they buy redistribute incomes and opportunities to try to level the playing field a bit more.

The Mincome experiment in Manitoba in the mid 1970s, the MacDonald Commission i n the mid 1980s, and the House Report from Newfoundland and Labrador in the early 1990s all had proposals for providing a basic income. Only Manitoba tried it, as a pilot project, for a few years. The problem with the guaranteed income idea is at what rate you set it, and at what rate you tax it back. It could remove the stigma of income support programs, but it could just as easily be a costly experiment that, essentially, guarantees poverty. Also, as Dr. Wilkinson has suggested, at some point on the GDP per capita curve, income inequality is no longer about material deprivation, but rather one of psycho-social responses. We are, after all, pack animals.

We can redress some of the vagaries of the market through public policies, but the root cause of growing inequality is how different peoples' work is valued. IN a slow growth environment, which seems to be the foreseeable future for Canada, it will become harder and harder for those at the top of corporate structures to take the types of increases they have been commanding in the marketplace and expect unionized workers to be happy about losing their pension, benefits and wage increases, and expect low-end workers to essentially stay put or lose more ground. Two things can happen - those at the top start moderating their increases; or those in the middle and the bottom start seeing solid increases, particularly as the wave of retirements starts accelerating. The problem with rising incomes, generally, is that usually goes along with rising prices; and we're about to host the largest cohort of retirees we've ever had in history, a group that lives on fixed and low incomes, to whom rising prices are toxic. So how will the highest priced workers get away witih demanding more in that context I wonder?

Historically, increasing economic growth first deliver rising inequality, then lowering inequality (Simon Kuznets' famous work back in the 1950s). That's still true of developing nations - economic growth is first badly distributed, then leads to demands for greater equality.

We can raise our kids more equitably - but it will take more taxes. We can have less of a winner take all society - but it will require some people at the top to trim their expectations. We can beat this in small ways, but we also need leaders to express the way forward. In the US they have Warren Buffett, Bill Gates and politicians leading the way. We're waiting for more people like Ed Clarke, the CEO of TD Bank, to weigh in on how to make Canada fairer (his suggestion is higher taxes on the rich).

One hope for turning this around in the future is education

Unfortunately, we won't know the answer until we actually improve education, then wait to see how our better educated young fare when they graduate, a process that will take decades. It will do little to alleviate existing levels of inequality.

redistribution of income is the only answer to our inequality problem

But won't such policies lower economic growth? No. Given the present, elevated level of inequality, a reduction is unlikely to have much of an impact on incentives that are important for economic growth.

If we want to preserve a growing and socially healthy economy, and avoid moving to points on the inequality curve curve associated with lower growth, then we will need to do much more redistribution of income than we have done over the last several decades. That means the wealthy will no longer get it all, or at least almost all; they will be asked to share economic growth with the workers who helped to bring it about, workers who ought to be rewarded for their growing productivity.

sharing economic gains among all those who had a hand in creating them is the right thing to do
