“and it was only WWII that got us out”
Wrong. In a purely economic sense, WWII wasted trillions of dollars. Plus, we had another recession as soon as war production stopped.
Actually, the US was making stuff for the Brits, French, et.al. for over two years before Pearl Harbor. They needed war materials, and we had the capacity to supply them in large quantities. Wasteful for Europe, but profitable for America.
I agree with you but from a societal viewpoint the war solved the huge unemployment problem, after eight years of FDR’s ridiculous government programs failed to do so.
You also make the mistake of equating a medium sized recession after WWII to the most extended and severe depression in US history. You are going to have to do way better than parsing and comparing apples and oranges to convince a reasonable person.
