If CEOs or others have big revenues, good for them. However, the thing I find the most irritating in the myth denounced in this thread is when it's reversed : "because I earn a lot of money, then that means I work harder and I'm smarter than others". This is utterly wrong and still vastly widespread.
Generally that myth is very strong in professions which are money-focused, such as banking. Many people decides their carreer according to other criterias than money: they just want to build something or be useful. That doesn't mean they are soft-workers or stupid.
