The FED's policies played a large role in that behaviour by lowering rates.
But I think many have a mistaken idea of what capitalism is. Capitalism is not anarchy, the absence of government. Regulations are therefore part of a capitalist system. Stated another way, government regulation is not the same as socialism.
One could argue that by the government controlling or a gov appointed central bank controlling the money supply, that in that sector alone, the control and issuance of money, we have adopted a socialist system, but that's pushing it to say so, imo. Capitalism does not negate the government's role completely.
