Without controlling for job title, how much does the average man make, and the average woman make?

I'm under the impression that the 77c figure is related to this "total" disparity, that better accounts for the separate, but related, issue of "predominantly female" fields paying less than male ones.

That's another issue entirely. Also you need to take into account things like maternity leave as well as women who man chose not to work full time, that bring that number down as well.
