Andrew Mellon in The 1920s
Andrew Mellon (1855–1937) was a millionaire financier who served as Secretary of the Treasury for 11 years under Republican presidents Harding, Coolidge, and Hoover.
As Treasury Secretary, Mellon pushed through a series of large tax cuts for the wealthy, freeing huge sums of capital for reinvestment in the booming stock market. During the Roaring '20s, Mellon was regarded as a genius of rapid economic growth. After the Great Crash, however, he was blamed by many for unwisely promoting wealth inequality and an unsustainable financial bubble.
