Here is a book by an outstanding professor of economics, who predicted the date of the crash of the end-of-90s economic bubble. Ravi Batra deflates Greenspan’s reputation as an economic wizard by presenting in great detail how Greenspan undermined the global economy. Batra calls Greenspan a fraud because Greenspan flip-flopped often in order to stay in the good graces of powerful people. Although supposedly a conservative, the main principle he followed was to always please the rich and powerful.
