WWII and the rampup was still a public works project. What really turned the economy for good imo was not WWII but the result of WWII -- all of our competitors on the international stage having large parts of their population and infrastructure destroyed. A few year grace period while the rest of the world rebuilt turned into 50 years of global corporate hegemony.
