Personally I think the biggest caveat avoided "when job differences are accounted for" is the care of children. Women, by-and-large, really get hosed with the negative externalities of having children (time off, career halting, etc). Most Western countries are not generous or equitable by half, and the USA is downright savage.
Sure, women who take time off to raise kids will take a hit to income. In a married family, the husband compensates. If the woman is unmarried, she gets child support/alimony to make up the difference. So, either you're arguing that child support/alimony is too low, or that married couples get hosed with the externality of having children. This is recognized in law, and people with children get tax deductions, and if…
There's a lot more to it than just that. If there was only a one-time hit to income, everything you said afterwards would hold true, but that's not the only issue, and you're quite naive for thinking so.
Also it shows poor faith in the community to hide behind a throwaway. I wouldn't down vote you for stating the opinion you just stated, but I will take the argument you just made less seriously because your making it in a cowardly fashion.
I take downvoting someone very seriously and will only do so if I think they are harming the community with their speech.
