Yea, so an employee should work hard to make money for the pleasure of the CEO buying another home this month? I rather work for my family, not for the CEO's one.
If a company doesn't want to pay me enough, I'm sure I will find another one.
Whenever you sell your labor, obviously the buyer of that labor thinks it's worth more than what they're paying for it, otherwise they wouldn't do it. So you're always working for someone else to make money unless you own your own thing.
It's just a question of degree there.
