We're a blended economy and always have been. We're not a fully capitalist or socialist economy. Economics has always been the story of who gets what, and why. It's pretty pointless to describe individual policies as capitalist or socialist We never were either of those.
What I do know is that the period of time that most people would describe as the most 'free market' economy created the most wealth inequality in history, an elite robber baron class ect. It also set us on the path to the Great Depression. The largest amount of growth and the era when more americans were lifted out of poverty, social mobility was at it's highest, wealth inequality was at it's lowest was when we had to most social safety nets.
We're veering towards the former, quickly. It would be pretty dope if we could shift towards the latter, and include non whites in the economic growth this time.
