You’re kidding, right? You quoted a technical paper on theoretical wage/price policy changing the entire course of the Great Depression. It would have been better to ask about QM!
Yes. During the Depression, all of FDR’s spending put together increased the debt by about $20 billion. WWII, on the other hand, increased the debt by another $200 billion. If they’d spent all that money beginning in 1931, instead of 1941, the Depression could have ended ten years earlier.
