I think it should be the other way round: if somebody thinks somebody else is being paid too much, they should have to explain why they think that is possible. That is, there has to be a market failure and they should explain what caused it.<p>Often the envy seems to be about jobs where people have little idea of what is involved. For example in banking or being a CEO. I guess most people have a rough idea of the importance of a doctors skill, so they complain less. I also see few complaints about artists earning millions of dollars. How does Beyonce justify her income - maybe she should be replaced by some random street musician?
