The other responses covered some reasons for this, but also men tend to accept more risk, more willing to devote their life to work or have a myopic focus. Again, less sane one could argue. It's a less balanced life.

Men hit the extremes more often and as a result occupy more of the outlier positions. They're also over represented at the bottom of the ladder. i.e., the homeless and prison populations. But I don't see anyone claiming it's a conspiracy that men over represent this end of the spectrum.
