I wonder the same thing. Why do CEOs get paid too much?
It was explained to me this way: in the US executive boards are unevenly weighted toward CO interests. In countries where wage experts and workers are more likely to sit on boards the ratio isn't absurd because boards are less likely to vote for higher executive wages (Japan and Europe have reasonable CEO wages).
Though I'm sure it isn't as insane as it is in the US.
