Warren G. Harding was the 29th President of the United States, serving from 1921 until his death in 1923. He is often associated with the post-World War I economic boom and a shift towards consumerism, which characterized the early 1920s in America. His administration promoted pro-business policies, tax cuts, and a return to 'normalcy' after the tumultuous war years, fostering an environment that encouraged economic growth and increased consumer spending.
