I AGREE WITH THE CANADIANS AND WITH MILTON FRIEDMAN

It appears that a number of Canadian economics professors agree with Stephane Dion, who proposed an unpopular carbon tax during his run for prime minister: "An Open Letter to the Leaders of Canada’s Federal Political Parties." [Linked to from Greg Mankiw's blog.] These sensible arguments are almost identical to ones put forth by none other than Milton Friedman in his seminal book, "Free to Choose." It's a shame that neither US presidential candidate is willing to go this route, pandering to our addiction to cheap oil rather than proclaiming we need to radically change our ways or die.
