In 1921, Warren G. Harding became President. He believed that the best way to make the economy good was for the government to be friendly to big business by cutting taxes and regulating less. While the economy was doing very well under these policies, America had the largest difference between how much money the rich had and how much money the poor had. Harding's presidency had several problems. The biggest one was Teapot Dome over oil drilling in the Navy Oil Reserve. Harding died in 1923, and Calvin Coolidge became President. Coolidge believed that the government should keep out of business, just like Harding, and continued many of Harding's policies. Coolidge chose not to seek the presidency in 1928 and Herbert Hoover became president.
