I must have missed it. Did the professor actually show that FDR’s programs ended the Great Depression?
Anyone who believes that the New Deal did anything other than to prolong the Great Depression is an idiot. World War II ended it. As FDR’s first-two-terms Treasury Secretary Henry Morgenthau stated for the record, the New Deal worsened things, not least by adding massively to the debt.
Adolph Hitler was more instrumental in ending the Great Depression than FDR.
