The US printed and spent tons of money during World War 2, and the postwar period was one of, if not the largest economic expansions in its modern history.
I see this argument come up a lot, I'd like to point out 2 points. 1) Wealth wasn't created during WW2, almost all of the increased production went to things like bombs and tanks and bullets, these things don't provide a real increase in quality of life this is one of the main points in 1984, people need to be kept busy, but Quality of Life can't increase. 2) The postwar boom was largely a result of everyone except A…
Either way, I think it's possible to argue that the US did generate Wealth in WW2, in the sense that it developed new technologies and knowledge that were eventually shared worldwide (I'm thinking mass production of materials like plastics, antibiotics, better research on nutrition, etc, statistical engineering techniques which eventually helped build up the Japanese auto industry), and that it trained a large portion of its population via the G.I. Bill and women working in factories, etc.
(None of this is to belittle all the damage done by the bombs, etc, and the US did have a massive advantage in non having it's production capacity wrecked like Europe, Russia and Japan. The broken window fallacy is a real thing)
