It doesn't really -- I don't think any business say "well, I'm paying for surgeons rather than pediatricians, which have more men, so I'll pay more." This would ignore obstetricians (more women) getting paid more than internal medicine (mostly men). Jobs tend to pay what the market works out is the lowest amount people will take the role for. This is the basic principle of supply and demand. Men tend to go to the jobs that pay more, the jobs don't pay more because men go to them. Not seeing this seems to be a massive willful ignoring of economics. Men tend to work longer hours. They negotiate more at hiring, as they are willing to take the chance that the request for more money fails and apply somewhere else.
