Capitalism as a classification/concept did not exist does not mean the practice did not exist. Capital (both in kind and in mind) accumulation has been occurring since even the stone age. Of course we would not call those societies capitalistic.
Plus I am replying to the comment that tries to dismember science from finance/economy.
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 as it is a form of governing.
