Having a kid is no longer high-status for women. The only women (in the US) having kids in excess of the replacement rate are the poorest and most wealthy, in other words those too destitute for child-rearing to bring them any lower, and too rich for the burdens of it to have any effect on them. For all those in the middle, pregnancy and raising a kid is catastrophic to free-time, career success, and a sense of freedom in one's life trajectory.
