I dont know when or how people got the idea that salaries are based on what a job is "worth" (a perfect tautology). Standard econ theory would predict salaries are based on supply and demand like everything else, not some metaphysical property called "value". If you don't like that, you need an economic system that doesn't base people's incomes on the market.
