IN THE MAIL: P.J. O’Rourke’s On the Wealth of Nations.

UPDATE: Reader Kevin Fleming emails: “I grabbed this one and read it as soon as I saw it in the bookstore. It’s well-written, smart, funny, learned, witty, acerbic, and a good explanation of tough material. I wish they’d make this a textbook for high school students. Hell, it ought to be required reading for Congress. Annually.”
