No, it really hasn't. You're suggesting that women actively seek out lower-paid, lower-status work. Just the other day there was an article on HN talking about a guy that was getting job applications rejected until he clarified his gender on his CV.

If you're a woman that runs into this discrimination, your only choices are to lower your standards for a job, and accept one that is lower paying, or to not work at all. All of a sudden the argument that women doing the same job get the same pay seems rather weak, because it's far from clear that women have the same opportunity to get the same job in the first place. All of a sudden, the lower remuneration of women is once again caused by discrimination, just not salary discrimination.
