I really don't like talking about things I don't have a good grip on. Batting around concepts in purely logical terms is fine, but in reality every system has its Tao, the natural way its component parts hang together and interact. For instance an automatic transmission doesn't operate logically and no amount of boolean logic will explain its function.
So, having had a really good salmon teriyaki in the Village, I hit Barnes and Noble and picked up Economics Explained: Everything You Need to Know About How the Economy Works and Where It's Going by Robert Heilbroner and Lester Thurow. When I'm done I'll see if I need to get deeper to talk rational shit.
I also got The Mystery of Capital by Hernando de Soto. The subtitle, "Why Capitalism Triumphs In The West And Fails Everywhere Else," indicates it covers some important material. It was an impulse buy, though, having never heard of the book before. Lots of props from conservative types, but that's not necessarily a flaw.
