> single men's expectations of potential partners are totally the prime suspect here.

It's both genders; women do not lack agency in the dating market. It'd be as fair to make "my partner should be willing to give up their career to start a family" as the default and blame the dynamic on women - after all, they prefer men who are unwilling to compromise in the pursuit of their career.

I try to avoid either, and just mention that this axis has a gendered component in terms of both what people do and desire.
