How does 7 years of 20% unemployment "Create a middle class"?
By changing the fundamental structure of the economy.
Dude, prior to FDR, there was no middle class in this country.
Heck..there was no middle class anywhere. We basically invented it.
Complete garbage. The middle class was created during the so-called "Gilded Age" when leftists claim that rich people were supposedly the "oppressors".
In reality, from 1870 to 1900, the prices of goods DECLINED while average wages for workers went up about 30-40%. It was also the fastest GDP growth per year (about 6.8% annually). Wages for all workers increased markedly in this era, and since progressive policies were put into place, this growth has slowed down.
Also, Hoover's LEFTIST policies helped cause the Depression, and FDR just doubled down on Hoover's policies. Specifically, Hoover's big-government tax increases and the Smoot-Hawley tariff made the depression bad. FDR's advisers admitted they were extending Hoover's policies, and many of the projects/agencies created were started by Hoover.
Remember, in the 1920's the GOP was divided into the Progressive(ie leftist) and conservative wings. Calvin Coolidge, who presided over a booming economy, was a member of the latter and Hoover was a member of the former. Too bad this fact is lost on so many people today.
