You don't have to work smarter or harder than everyone else - you're in the driver seat and make the call about strategy which will make or lose the company big %'s of its revenue which has huge value.
I've seen quite a few CEOs of companies I've worked at where most of the employees could make a lot better decisions. You probably have as well.
These "people in the drivers seat" are often not very good drivers. Some are. Most are terrible, and while the company (the collective of all the people working there) may be making "huge value", it is by no means certain that it could not be making 100x more - and sharing it better with the people underneath.
CEOs are just humans, like you, who happen to be leading something. They do not have magic brainpower skills.
So fire the bad CEOs. I did not imply that all CEOs are all good drivers, and it doesn't matter if some are. They are in the position to make decisions that change the course of the company, whereas an individual engineer or sales person isn't doing that, and doesn't have that responsibility. Magic brain power skills are not required so I am not sure why you are bringing that up.
