Also people aren't paid what value they provide to the company, but what they can negotiate for - for example, if you need your job then your boss can get away with paying you peanuts even if you do 3x the work of your colleagues. Incidentally, this is the basis of unions - the union negotiates your salary with the union's negotiating power of having the company's entire staff walk, which hurts far more than merely losing one employee.
