Earlier quoted context omitted.
CEO takes two weeks off. What happens to the company? 10,000 "low-level" employees take two weeks off (all at once.) What happens to the company? Companies operate without CEOs while boards seek candidates. Companies can't produce product while it seeks 10,000 replacement workers. As long as we have the chief executive on one hand and the workers on the other, that is.
If you permanently eliminate the position for one line worker, there is essentially zero impact to the company; it continues along with only a 0.01% drop of efficiency. If you permanently eliminate the CEO position, there is multiple orders of magnitude greater impact to the company. That's why the compensation for each role is different.
I take it you're a Communist then, and follow Communist thinking in other economic thought as well.
The classical economic theory of pricing holds that goods (and labor) are exchanged at a point where the supply and demand curves cross. This, according to the principles of free markets as expressed first by Adam Smith and subsequently refined, and has certain prerequisites including low barrier to entry, equal access to information, fair and open competition (and a lack of collusion on the part of either buyers and sellers), and a clear understanding of value.
All of which undoubtedly hold true for the CEO employment market, I trust.
