People that think it’s purely an economic problem are wrong. Economic and political solutions are not enough. You also need social solutions too. Like make it cool to have kids and solutions that allowa women of child bearing age to be around other women who have young children
Having children in modern society is pretty isolating. We had it very good because our neighbors have children of similar age and we could share the burdens of cooking and watching them while simultaneously also seeing other adults. If both parents work and you do all your chores you have approximately zero time to socialize outside your immediate vicinity. It takes a village but nobody has a village any longer
