What if peoples relationships create a superstructure no single human can control, and we need active collective effort to supercede it?

If a single human refuses from a moral standpoint, a humongous amount of money to do something crap as CEO controller of whichever crap company, boards will replace them, and some other human will, because material condition dictate it has to be done. No one is really in control. The boards are all just optimising for profit, because if they're not, someone else will.

How to break the capitalist cycle of control over peoples will?
