Written in O’Rourke’s typically humorous style, this is a serious book. Dissatisfied with works on economics he had read, he set out to find out which economic theories work and which are a waste of paper. He studied places as diverse as Tanzania, Sweden and Hong Kong, to find out which applied theories actually produce the most benefits for the people. This is a great primer on economics for a sensible person. It demonstrates the foolishness of believing in the promises of Socialism, and shows that free people, free markets and the rule of law are the most important ingredients for a successful economy.
