The Business Plot was an alleged political conspiracy in 1933 in the United States. Retired Marine Corps Major General Smedley Butler claimed that wealthy businessmen were plotting to create a fascist veterans' organization with Butler as its leader and use it in a coup d'état to overthrow President Franklin D. Roosevelt. In 1934, Butler testified before the United States House of Representatives Special Committee on Un-American Activities (the "McCormack-Dickstein Committee") on these claims.[1] No one was prosecuted.
This came up in a discussion about the real impacts and outcomes of the depression VS the story of October 29, 1929. There was a great point that pretty much no one owned stock (less the 3%), but in 1931 over 2300 banks failed, then life changes. I'd never heard of this supposed coupe, and certainly General Smedley Butler sounded like a joke.
