Actually we have known for a long time that most people's salaries are completely decoupled from the value they create. I've never seen anyone claim the opposite except for business owners and middle management.

Everyone wages are more so tied to how much leverage they have. Increasing one's output has never been a great recipe for increasing compensation, however, increasing your leverage (get a new offer, get a government certified monopoloy, lower the supply of people with your skills, etc) will do wonders for your wage!

Seriously, though.
