My understanding is that the CEO's in question are not even remotely comparable to Lebron James's stature in basketball.
Businesses compete against each other and the CEO orchestrates the strategy and is accountable for the the execution across a broad spectrum of functions. There is a power law distribution where the very best CEOs are vastly superior to the good who are to the replacement level ones. So like in the NBA you may overpay for a guy in the hopes they are great or you pay handsomely for a good player that is above replacement level or you pay the highest for the best to run your company. Sometimes it pays off and sometimes not.
But the value that great CEOs produce is astronomical. Well more than a basketball player could ever hope to produce.
