In this completely unique book, the economist Mason Gaffney puts together one of the most carefully researched, sharply witty, and engaging historical non-fiction works I have ever read. The claim seems incredible... and for years, even as a geoist, I didn't really believe the talk. Not until returning to my university and questioning my former economics professors was I persuaded to read this book and take the issue seriously. I highly recommend this book for anyone interested in history or economics; no special training is required to understand, though you will almost certainly want the aid of a dictionary.
