“Notably, Chang’s report claims that biological females develop earlier than males do, so requiring girls to enter school at younger ages will create classes in which the two sexes are of more equal maturity as they age. This, the author posits, makes it more likely that those classmates will be attracted to each other, and marry and have children further down the line.”

“The report does not include evidence of any correlation between female students’ early enrollment and the success rate of their romantic relationships with men. The author also does not detail specific mechanisms by which his proposed policy would increase romantic attraction or birthrates.”
Not just work life balance, but also the cost of living. I can barely afford to take care of myself, so I’m completely disinclined to go and create a whole new person that will be absolutely dependent on me to provide for it for years. If people can afford to live reasonably comfortably and conditions give them confidence that conditions will remain stable for the next 10-20 years, I bet you’ll see them start having kids. When they’re worried they could be homeless next year if things worsen and their retirement plan is advocating for the right to end one’s life on their own terms, it shouldn’t be a shocker that people don’t want to add kids into the mix.
Also, perhaps decades of social stigma that said having a bunch of kids is something only poor, ignorant people do that represents a moral failing amongst the upstanding daughters of decent society is a bad thing to maintain when you want folks to keep cranking out more kids to feed into the meat grinder of the workforce.
