If you have 25 minutes or so this is a very good video on interview of Milton Freidman. If you like big government and rampant government spending programs, this video is not for you. I often find it quite instructive to watch old videos from some considered leading economic thinkers of their era. Much like Heyak saying Keynes thoguht of economics as a sideline yet the world today is full of keynesians believing somone who wasn't even an economist nor knew or understood economic history, not sure how this happened but it did.
