Couple points: not every job is "truck driving" (and even then a CEO is not guaranteed to be able to drive a truck, that actually is a skill), but as I gave the example earlier: I'm a PhD scientist. I work in a chemical lab. There are only a tiny fraction of Americans who have a PhD. The CEO of the company I work for only has an MBA. There are many, many more MBA's than PhD's. It requires many more years of work to get a PhD.
Why do I not make 150 times what the CEO of my company does? The CEO of the company I work for would actually probably hurt themselves in my work place before they'd be able to do any good, such is the nature of our different jobs.
AND, without the research scientists in the company the company would have a very tough time competing.
The CEO, without benefit of all the work we do, would be just another suit sitting in a big empty conference room.
So why would a PhD make much less than an MBA?
Seems your argument fails.
