Three Republican Presidents run the United States during the roaring twenties; namely Warren Harding, Calvin Coolidge and Herbert Hoover.
They adopted a policy of free market well known as laissez-faire, according to which, the government should not intervene in the economy.
Warren Harding pledged a return to normality. He reduced taxes to grant businesses more money to grow and to inflate the pockets of ordinary Americans. In 1922, he introduced the Fordney.McCumber Tariff Act which imposed a tax on goods importeds from foreign countries.
Calvin Coolidge adhered to the laissez-faire policy and gave businessmen the freedom to make a profit and become rich.
Herbert Hoover started ruling in 1929 and he pledged to "put a chicken in every cooking pot, and a car in every garage". He advocated for the laissez-faire but he also believed in rugged individualism, that is that people should work harder to solve their problems instead of depending on the government for help.
