Do you have evidence for your assertion? Of what significance is the ratio of highest to lowest paid employee? Shareholders of a particular company pay CEOs, not whoever "we" is.
Producing more value than you are compensated for ... hmmm what does that sound like? You could say it sounds like the human condition. Which employees in the pyramid do you think have the worst scalar here?
This may be true for CEO’s turning dysfunctional companies around on personal authority, but I find it hard to believe for companies that are already running perfectly well.
