Y'all are all missing the real answer. CEOs have class solidarity with shareholders. Think about about how they all reacted to the death of the United health care CEO. They'll never get rid of them because they're one of them. Rich people all have a keen awareness of class consciousness and have great loyalty to one another.
Us? We're expendable. They want to replace us with machines that can't ask for anything and don't have rights. But they'll never get rid of one of their own. Think about how few CEOs get fired no matter how poor of a job they do.
P.S. Their high pay being because of risk is a myth. Ever heard of a thing called the golden parachute? CEOs never pay for their failures. In fact when they run a company into the ground, they're usually the ones that receive the biggest payouts. Not the employees.
The math has never made sense for CEOs
