Economics in three sentences

Scott Adams in The Dilbert Principle:

I don't know why the economy works, but I'm sure it isn't because brilliant people are managing it. My guess is that if you sum up all the absurd activities of management, the idiocies somehow cancel out, thus producing cool things that you want to buy, such as Nerf balls and Snapple. Add the law of supply and demand to the mix and you've pretty much described the whole theory of economics.
