It has been claimed that sending women to college or letting them have a higher education lowers the birth rate.
But what type of material is taught in these classes? "Feminism"
If they went to school classes that taught them reading, math, real physics, biology and chemistry AND taught them a worldview that supports women giving birth to more babies instead of "feminism" then you could use schools to raise the birth rates
This would involve removing social "sciences" and removing other lies
