First of all, thank you for a cogent exposition of a difficult subject. I could quibble on many points, but the only one I really feel strongly about is your equating “capitalism” with “free markets.’

Free markets are the last thing any capitalist wants. Every capitalist wants more than anything to be a monopolist.

Almost all markets in a capitalistic economy are what’s often called “monopsonist,” meaning they aren’t quite monopolized, but are far from “free.” The nature of capitalism — defined by large-scale production — makes entry into capitalistic markets financially (and often technically) dauntingly challenging, which of itself, by the nature of the system, discourages competition.
