There's also the major factor of children. Women get a lot of scolding from society if they prioritize their career over children. Men generally aren't shamed to such a degree, and workaholic dads are even lauded as being "diligent bread winners." Also, for many moms, working late in the office isn't even an option. They have to leave the office before day care closes. Or, in the case of women who can't afford day care, they have to take inferior job offers with inferior hours to work around their kids' school and care schedule. These things can make it extremely hard to be viewed as "managerial material" and rack up promotions. (Of course, dads face these issues too, and single dads have it especially hard. But it's statistically more likely to impact moms.) Also, men just aren't as concerned over how much their significant other makes. Women, on the other hand, tend to more heavily judge the worthiness of a date on their career and income. So there's more incentive for men to chase after high paying, high power careers.
