He's not running for election
He's running a think-tank - The Broadbent Institute, named after him.
Broadbent is not seeking votes. He's out to influence people and politicians, to try to get them thinking about other Canadians instead of themselves.
Broadbent says the middle class is disappearing. The rich are getting richer, very rich in fact. The poor are as poor as ever.
When Broadbent retired in 1989 from active elected politics, 14 % of Canadian children were living in poverty. Today 14 % are still living in poverty. Nothing has changed. That's what bothers Broadbent.
He wants politicians at least to think about what he calls "income inequality." Call it taxing the rich if you want. Taxing them at the same rate as in other OECD countries might be a start.
Meanwhile Stephen Harper keeps giving the rich tax breaks, lowering taxes on their big corporations -- 16.5 % to 16 % to 15.5 % and down it goes year after year while the country keeps on running up a Harper deficit six years in a row and piling it on the national debt.
For the middle class, Harper puts their Old Age Security back another two years, from age 65 to age 67 Great! Freedom 65 becomes Freedom 67.
Broadbent says we need more affordable housing for the middle class, and more child benefits, not less.
His tax-the-rich suggestion won't get a hearing from Harper, the best friend the super-rich ever had, and not much either from "Honest Tom" Mulcair. He's an old Liberal. Nor are the waiting-around Liberals likely to get all excited.
So don't expect Canadian society to be tagging along anytime soon with Broadbent, the guy we used to call "the best prime minister we never had." But at least he makes us think. And for that, we are grateful.
