Simply Superb and Fascinating (at least to me)
Format: Paperback
While some may find this book boring, I find it fascinating. Professor Hudson is not only a brilliant writer, he is a mind blowing researcher who references everything. I have become fascinated with things like the USA lend-lease program that the USA implemented in World War 2 and how it damaged Europe, Britain in particular. Hudson covers this in detail. My personal study of economics for years has focused on John Maynard Keynes vs. the "Austrian/Von Mises" school and their so called "free markets." Professor Hudson, who anyone who has an interest in economics should get to know, is a TRUE "free market" supporter, a TRUE supporter of classical economics and offers a third and viable alternative to both Keynes and the "Austrian" school. VERY different and oh so fascinating. I will be buying more of Professor Hudson's books and recommend that you investigate the writings of Professor Hudson and also that of his friend and fellow economist, Professor Richard Wolff.

Best post 1900 historical reference book I've read.
Format: Paperback
Best historical reference book I've read - explains the rise of the US since 1900 at the expense of the rest of the world. War and trade is a business model the US has ruthlessly exploited - Hudson has recorded the ugly, callous methodology.

The paradigm of Dollar supremacy
Format: Paperback
Michael Hudson demonstrates how dollar dominance allows the U.S. to sustain trade deficits and fund overseas commitments by exporting its debt. This system gives the U.S. unique financial advantages, enabling it to shape global economic flows while minimizing domestic strain.
