Shame they cant address the root cause:

Thw root cause is giving women agency. Careers education etc and mostly free of religious indoctrination (eg Quiverful etc)

If women have a choice, the majority choose 0,1 or 2. For every woman that chooses 0, you need another woman choosing 5 just to tread water. Hungary and Poland are throwing a fortnue at it and gerting no where, as is Russia. Australia, Sweden etc all have less then replacement, the only reason Australia keeps growing it’s population is immigration. You either do that, or you take away womens right to choose, or your population goes backwards. (Or aim for some sort of stasis where deaths = births + immigration)

You can’t grow the population forever, so you have to address the issuie at some stage anyway.
