I'm not sure why it's obvious that the CEO should be the highest paid? Why should everybody's boss make more than them? I know that isn't the case for many line managers of highly-paid programmers, for example, and I assume the same is true of other similar professions, at least sometimes. Wages are theoretically a market, and probably it's often easier to replace a skilled manager/business bro than it is a skilled engineer/artist/salesman, and often it's more important to your business.
