There is a difference between starting a career and taking a break from an established one. The women this subject discusses try to do the latter because the former requires both the care of very young children and a major time investment in early career building. I.e., the problem is the time needs of mothering very young children.
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.
