Good question. ;^)
One of the problems with politics grounded in economics -- whether you're Marx or one of Milton Friedman's acolytes in Congress -- is that economics confuses wealth with happiness: a wealthy life with a happy life. At least Marx understood alienation of labour.
If you're going to be unhappy you might as well be rich, I always say.
My friend Deb sent this to me. It's a good job -- although the Aristotelian in me has to note that Professor Kozy got Aristotle a bit wrong. Aristotle noted trenchantly if not tragically (in Nicomachean Ethics Book X) that ethics only works if people are rational and, since they aren't, we have to make due with politics instead.
