Wealth of Nations by Adam Smith is often quoted and talked about today, but no normal 21st Century reader is going to read it. This book, "On the Wealth of Nations," makes it accessible to mere mortals. Of course O'Rourke tries to be funny whenever possible, and his quips did cause me to smile from time to time. However, I don't recommend this book for comic relief. I do recommend it for anyone who wants to be reasonably well informed about the history of the study of economics.
