Well, CEOs are increasing their performance at all important job metrics, at a much faster pace than any unimportant "worker" has done, in all of history.
Just look at stock price, dividends and/or executive compensation. They are obviously much more important than the people who actually make the product, provide the service or interact with the customer. For any actually important metric, CEOs add more value to the people who determine what value the CEO adds more than any other part of the business.
This must be why CEO pay, relative to worker pay, has increased so much over the last few decades!
