There was always skepticism about claims that, as the rich became richer, income would "trickle down" to others. What wasn't perhaps foreseen was that the trickling would actually be in the other direction, and that it would be more of a torrent than a trickle.

But the evidence is now clear. Over the last three decades, the tables of the rich have overflowed, with barely any scraps falling off. On the contrary, there's been a massive transfer of income and wealth from Canada's middle and lower class to the rich.

The result is that Canada has become a highly unequal society.

Nobody ever accused Barack Obama of having too stiff a spine.

Even so, there is something crushingly disappointing about reports last week that the U.S. president is likely to retreat from his promise to cancel George W. Bush's tax cuts for the rich.

Such a capitulation to the Republicans would concede defeat before the battle to achieve greater equality and to "spread the wealth around" is even waged. The audacity of hope seems to have turned into a readiness to choke.

Obama's promise was a modest one -- to push the top marginal tax rate from 35 per cent back up to its Clinton-era level of 39 per cent.

Almost 40 years ago, Ottawa quietly cancelled Canada's estate tax.

Few Canadians even knew about the tax. Those who did mostly belonged to a small number of wealthy families who were rich enough to pay it. With its cancellation in 1972, this tiny crowd was suddenly a lot richer.

U of T economist John Bossons calculated that ending the tax amounted to a windfall of about $12 billion ($62 billion in today's dollars) for Canada's wealthiest families.

The removal of the estate tax, which remains an obscure event in Canadian history, had momentous implications, depriving Ottawa of revenue and putting Canada on a path toward greater inequality.

It's not often we get a chance to glimpse how power really operates in Canada. Last night was one of those rare opportunities.

At 6 p.m., the men who dominate our financial system assembled at the Hilton Hotel in downtown Toronto. Among them were the CEOs of Canada's five big banks and the top insurance companies. In many ways, this crowd could be regarded as the executive committee of Canada's ruling elite.

They came for a dinner ($1,250 a ticket) to raise funds for a new monetary policy research centre connected to the C.D. Howe Institute. That may sound innocuous. But Canada's top bankers were not getting together to figure out how they can make banking more customer-friendly.

The good news is that there are still some tickets left for the Fraser Institute's 35th anniversary gala dinner next Monday night in Vancouver. The bad news is that the tickets -- including tables for 10 at $7,000 -- will probably all eventually be sold.

And that means yet more money flowing into the amply filled coffers of an organization that for 3 1/2 decades has worked tirelessly to cut taxes for the rich, undermine public health care, destroy confidence in public education and prevent Canada from joining the global climate change battle.
