Smashing the Glass Ceiling?

I just had a stimulating and enlightening discussion with Kail (conversations with Kail tend to take that track, no matter the topic). We were discussing dating, gender roles, and many other topics in that general family, when he mentioned something that was news to me -- the glass ceiling has, for a certain control group, been broken. While I don't have any articles to site, Kail is a pretty reliable source (he has his Masters and is working towards his PHD in Economics). Apparently, if you control for women who take time off to have children (i.e., this statistic applies only to women who do not take time off to have children, which generally overlaps with the times women are most likely to receive key promotions), women will make more money than men on the same career path. I realize that for the vast majority of women I know, this is a non-issue, because while careers are important, our ultimate goals include family. But for the sake of progressive society, that's pretty amazing to me. I've long worked with the assumption that if a woman and a man, on the same career paths (in private industry), with equal qualifications and experiences, went head to head, the man would undoubtedly earn more. While I ultimately would prefer an equal pay for equal measure type of system (yeah, I'm an idealist, news flash), I think it's refreshing to hear that women who sacrifice their traditional gender roles are being compensated for it. That's my 2 cents.
