I do see why CEO's (and all c-level if they are founders, have board seats, are early investors, have a high amount of %) should be compensated well over employees; they take the risks. Or rather; they should take the risks. If times are bad, I am looking to work with people who cut their own salary or reinvest to keep the employees and not just throw everyone out and take the bonus and then close up shop (which seems to happen a lot with startups right now).
200x is over the top I guess; I cannot see how you bring that much more value than your employees. Like said; no idea how it works at real enterprises, but in companies I see with few 100 to few 1000 people; I can walk around and remove a few dozen people (employees) and the entire company will grind to a halt. There are always vital things that are governed by a few (early?) employees which, if removed, are extremely hard to replace. This means that at least those employees cannot earn 200x less than the CEO, not 100x less either.
I saw a post on Twitter a few days ago about those kind of employees of these kind of companies starting a company together, resigning and then having the new company acqui-hired by the old company for many millions. That's how you should handle that situation if you have a CEO that is that greedy indeed.
