Earlier quoted context omitted.
You are confusing CEO pay with CEO ability. There is plenty of examples of companies doing poorly until a new CEO comes in, and others of a company doing well until the CEO retires and a replacement comes in. Ivy types have a poor history of figuring out which is which in advance though.
I think it's the other way around. They're not talking about CEO ability, they're talking about CEO performance, which aren't the same. Money follows performance (based on outcomes, not actual talent). It's like professional sports - win a championship, get a big payday, regardless of how it happened.
It's an extreme abuse of power, especially since workers are the sole reason why a company is able to succeed or not and they don't get the same privileges as a board + executive.
Not too mention most corporations + startups are setup to encourage the worse forms of human collaboration (dictatorships + centrally planned economies).
