Thorough history
Format: Hardcover
Levy provides a masterful history of American capitalism. His work is detailed and brilliantly written.
You should buy this book for its last section: the age of chaos. Here Levy details the US economy since Reagan and identifies critical trends and questions we all need to address.
This is not a book for a casual reader, each chapter is hard work. However, the rewards more than outweigh the effort.
