It’s entirely possible that this is causal ABs deliberate, ie the reason why boards of these companies have approved large CEO pay packages is so that the CEO will align themselves with the shareholders paying them rather than the workers working for them and cut wages so the money can be returned to shareholders as buybacks.
If anything, they're paying CEOs so much in some cases that the rational thing for the CEO to do is as little work as possible. Why work hard if you'll get enough to retire comfortably on regardless of your performance?
