Free market and capitalism are mutually exclusive as in the theoretical model that is the free market, with perfectly rational actors and information, a capitalist class cannot exist, they'd quickly get competed down to size.
Unregulated markets and capitalism, now that's a lovechild, as without regulation real-world markets quickly turn into monopolistic shark-tanks instead of free markets, actors not being rational, information not being perfect and all.
