Her first link ("women earn more than men in their 20s") goes to an article that ascribes the difference to a larger number of women at that age having degrees - ie, all else being equal, women earn less than men for the same job. Her second link ("women choose to downshift") links to an opinion piece that provides no citations for any of its claims. Her third link ("Women are choosing children over startups") links back to her own blog and again provides no substantive citations.
If someone's going to make blanket assertions like this then they ought to be able to back them up. She hasn't.
I recall an article posted to HN several months ago that echoed her assertions.
It showed that single women in their 20s were earning as much, if not more, than similarly skilled men. But those earnings, relative to men, declined as they started getting married and having children.
So yeah, it would have been nice of her to cite it, but the data is out there.
