The pattern seems to hold true though, with a family I know. There are four children. The oldest son graduated and got a law degree, he got married, to another professional, and she is expecting. The next child, a daughter, got a degree, and a job, but she has a boyfriend, and at this time, there is no serious talk of marriage. The third child, a male, got a degree, got a job, and is engaged. The fourth child, a male, is still in school. I am betting that soon after he graduates, there will be a woman and an engagement. Kind of illuminating.
Few fathers are willing to invest the time in care of very young children and fewer are any good at it. Mothers are better at it due to biology, which likewise makes it almost impossible for them to not spend the time with their children that the children need.
The professional women at issue are in plain denial of biology. It is very difficult for them to do what they want so they both deny and resent that. But denial and resentment doesn't change the cards nature gave us all.
