In 1943, 1944, and 1945, the US put ~35% of GDP into war production, which helped win the war but, in general, produced stuff that had very little utility in civilian life. Judging by what some people are saying, throwing away so much GDP should have significantly increased the civilian death rate – but it did not. For that matter, the Great Depression didn’t materially increase death rates.
1943-1945 should have tanked the economy and blasted health, according to them, but that didn’t happen. Not even close.
Why not ?
