Best post 1900 historical reference book I've read.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Best historical reference book I've read - explains the rise of the US since 1900 at the expense of the rest of the world.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.
