Economics in One Lesson

I just reread Economics in One Lesson, by Henry Hazlitt. It's short, and available on the web for free at http://jim.com/econ/contents.html. A fantastic explanation of why free trade is good, farm subsidies are bad, imports equal exports in the long run, etc. Written in the 1940s and updated in the 1970s, but pretty much everything in this book is still very relevant. Recommended.
