I enjoyed this, but Landsburg is oddly didactic and condescending - you get the feeling he thinks many people are unutterably stupid, which is a perfectly fine opinion to have, but not one you want your reader to feel you have about them. The final chapter in the book, entitled “Why I am Not an Environmentalist,” is particularly high-handed in its tone. It’s also interesting to be reading a popular economics book that’s 15 years old now; I’ve read a lot of similar, more recent books (and several economics textbooks) and some - certainly not all—of the analyses in Landsburg’s books seem almost simplistic to me in comparison. Clearly the field has deepened in sophistication a great deal since then.
