I shouldn't speak ill of the dead
but Milton Friedman is, was, and always will be a douchebag. I never liked his "Free to Choose" philosophy (as one economics instructor I had noted, "free to choose" = "free to die"). More specifically, I thought that he was a hypocrite. He trashed public education and public universities in his books, yet he benefited from both. Jerk.
Anyways, Paul Krugman revisited Friedman's notion that the Federal Reserve Bank could have prevented the Great Depression. Or that it caused the Great Depression. (He notes that it expanded the monetary base, big time, and it's not working.)
Meh.
