Where orders emerge.
If you don’t know who Friedrich Hayek is than you’ve missed a very important book on economics, The Road to Serfdom.
Along with O’Rourke’s Eat the Rich, Sowell’s Basic Economics (nice review here), and Freidman’s Free to Choose, it should be required reading for high school graduation.
Cafe Hayek is a nice intersection of economics with the real world.
This post, on rules for children watching television, is a good example.
