While politicians in Ottawa still can't decide who is in the middle class, a new analysis suggests wealth is increasingly gravitating to the very top.

The report by the Canadian Centre for Policy Alternatives shows that the country's 86 richest individuals and families — or 0.002 per cent of the total population — are getting exponentially richer and now have accumulated as much wealth as the country's poorest 11.4 million.

That's more than in 1999, when the richest 86 had as much money as the poorest 10.1 million and enough to buy up everything in New Brunswick and still have about $40 billion left over, according to the report, to be released Thursday.

The point of the exercise, says economist and author David Macdonald, who used Statistics Canada data and research from Canadian Business magazine, is to show that if income inequality is a policy and social justice concern — wealth inequality is worse.

In fact, the super-rich list of Canadian residents has little to do with income in the traditional sense, he said. None of the 86 are company CEOs — often the poster children of the Occupy crowd for their unseemly salaries and bonuses. Instead, the ones on the list are there by virtue of being company founders or related to company founders.

The super-rich have gotten there by creating and trading assets, whether companies, real estate or securities.

"We often focus on income inequality but that's a socialist paradise compared to wealth inequality," said Macdonald.

"The top 20 per cent only get half of all the income, but in terms of wealth inequality, the top 20 per cent have 70 per cent of all wealth. It's much more extreme and the concern is as you accumulate all this wealth, this wealth starts to buy you political power."

Inequality, whether in income or wealth, increasingly looks like it will become a key issue in the upcoming federal election, with Liberal Leader Justin Trudeau and NDP Leader Thomas Mulcair seeking to make the case that Conservative policies have left the middle class behind — with little job security, higher in debt, and in many instances, living paycheque to paycheque.

The government has pointed to the growth in net worth most recently reported by Statistics Canada in February as an indicator their policies are working for everyone.

"After-tax disposable income has increased by 10 per cent across all income brackets," noted Employment Minister Jason Kenney at the time.

But Statistics Canada also showed wealth gravitating to the top. While median net worth rose almost 80 per cent since 1999 to $243,800 per family unit, the top 40 per cent possessed 88.9 per cent of total net worth, leaving the bottom 60 per cent with a mere 11.1 per cent of the pie.

Eye-opening was the data that showed the poorest 20 per cent of family units had more debts than assets.

Debate over middle-class

The issue flared again Wednesday after Trudeau asked Prime Minister Stephen Harper if he thought that the problem of the middle class was a myth. Harper chided Trudeau for his inability to define the middle class.

But the issue is not going away. The NDP has been especially critical of the government's decision to severely cut corporate tax rates, even in the middle of a recession, and getting little job creation or business investment in return.

Some economists have also argued that nations with high levels of inequality tend to underperform more egalitarian countries in terms of overall economic growth.

The latest CCPA analysis also suggests that once someone gets to the top of the wealth ladder, they likely stay there.

The richest individuals and families in 2013 were pretty much the same people who made the list in 2005 and in 1999 — well-known family names like Thomson, Weston, Irving, Desmarais and Pattison.

Between 1999 and 2013, the report shows that the wealthiest 86 Canadians had enlarged their pot of gold from $118 billion to $178 billion on real non-inflationary terms.

Macdonald says a reason wealth growth is increasingly becoming concentrated is that it is taxed differently from income.

"If one Canadian makes $100,000 a year selling a company (or shares) while another makes $100,000 a year working at a job, the worker will pay twice the tax of the business seller," he said.

"A combination of a higher inclusion rate (for capital gains) and higher income taxes at the top of the income scale could go part way to offset the flood of wealth that is accumulating in the pockets of Canada's wealthiest and ensure some benefits are returned to the majority of Canadians."
