Transparency solves that problem. If below average workers moved from business to business getting paid less than their peers, how long do you think they would consider themselves better than average?
Never underestimate the ability of people to come up with all kinds of reasons why they are being treated unfairly.
We have a tendency to put too much value in what people say rather than how they act. I'm confident actions would reflect people understanding their value in a transparent world, even if their words did not.
This is a small minority though.
I'm sure some would come to the conclusion you suggest, but I fear many would fall into a victim role and point fingers.
