But the free market is an ideal which is easy to game. CEOs hand picking the board, and the board then turning around and deciding on the CEOs compensation is an example of the free market being gamed.
It's a bit more complicated then that, it requires the government enforced and defined legal entity that is a corporation, but it's still market inefficiency, mostly agency risk.
So in a way, it is the public's concern to remove market inefficiencies.
