In 1945, we operated under what was functionally a command economy at the tail end of a globe-spanning total war.
I mean, we can debate the efficacy of that economic model (re: The People’s Republic of Walmart), but I’d rather the US be funding and fighting fewer wars, not more of them. FFS, if you give any number of shits about climate change, a global mobilization of killing machines is not going to point us in the right direction.
