No doubt the mostly defense spending you describe provided fiscal stimulus to the economy and led to the benefits you list, but that's not the same as a subsidy

No doubt the mostly defense spending you describe provided fiscal stimulus to the economy and led to the benefits you list, but that's not the same as a subsidy, which would mean something like Section 8 vouchers. The real driving force was that wage growth massively outpaced costs. After the war ended it was routine to pay off a 15 year mortgage a decade early, because real wages rose so much. Similarly, our current lousy situation is the result of median real wages staying flat for decades.
