Query: Excellent text tying together Economics and World History

David Landes is an enjoyable story teller and writes in a very readable manner. He explains, with amply researched proofs, why various countries have developed the way they have. I learned alot about world history as well as economics and how geography, culture and government have all interacted in the world to explain the economic history of the world, why some countries are rich and others are poor.
