I'm confused as to why you think that just because two concepts are abstract they can't interact with each other. How do you explain that logic?
Do we claim that capitalism cannot produce hyper-greedy sociopaths? Because I would argue that it distills those people better than most systems. We need some form of modified capitalism which has some checks and balances. We did have that system for a long while, but the controlling agencies got captured by private interests and we can all plainly see the risk involved there.
But it's pure capitalism. People who say pure capitalism would have an even playing field discount the possibility that the winners on that level playing field would change the playing field to benefit them forever. What is keeping the playing field level? Not the market. The market doesn't limit systemic drift.
