So are you saying, after the New Deal, the US was/is no longer practicing capitalism? I am afraid I have to disagree.
The US government did not produce all the technologies. Many of them are from private companies. Yes the government funded them with public money, public money paid by the taxpayers.
We have a mixed system. But we are capitalistic leaning are we not? Being capitalist or socialist are not discrete choices, but a continuous scale. I agree with you on that.
Btw the 1929 great crash was facilitate and exacerbated by lax Federal Reserve control of money issuance and the drastic tightening after the crash. This is actually an argument against centralized money.
Well a joint stock company also does that. It engages in production. It does redistribute wealth. For a long time, public services e.g. firefighting, were provided by private entities. Is it socialism? I don’t think so. It has to involve coercion, say, via monopoly of violence to be socialism.
