No, the answer seems to be that CEOs are incompetent, talk corporations into giving them huge pay packets (which is done with the help of other CEOs), and generally don't have a clue of what they should be doing.
The compensation of a CEO is not tied to performance, so they can be as idiotic as possible, ruin the company, and still have their huge payout.
Basically, CEOs have hoodwinked the world into believing they're extra special people with valuable skillsets, even when they don't.
Essentially being a CEO is a great scam, funded by the shareholders and the employees. Being a CEO has to be the easiest fucking job in the world .. because no matter the shit job you do you still make a huge sum of money, and people subsequently are willing to hire you in other companies on the assumption that, having been incompetent to be a CEO already, you're qualified for the job.
In my experience and observation, your average CEO is either a failed business person, or an engineer who got lucky in another company and now has an MBA ... they're just chimps who get paid vast sums of money if they win or lose.
And, of course, since the people who hire and fire CEOs are just as incompetent, and in on the scam, they will never decide to tie compensation to any meaningful level of results.
Cynically, I believe this is just a massive scam being perpetuated to make a bunch of assholes even richer, while not giving a crap what happens to the company or the stock price.
Me, I'd be an incompetent CEO for half the price ... and I'd probably do no better or worse, and then I'd get my severance package and retire.
A fucking drunk chimp could do as good of a job as most corporate CEOs. This is just another example.
