What you're saying is entirely correct. But the simple fact of the matter is that men are not having children either. Consider the welfare queens discourse. It's mysoginistic (why not welfare bums?) but it's also aimed at anyone 'not doing their part' by getting a job, paying taxes and so on. This allows everyone from the rural poor to the suburban middle class to see themselves as Not Freeloaders®, and potentially soldier for conservative policies.

The demographic transition is not like that at all. Nobody is having kids. What tradmorons don't realize is that this isn't ideological. It's not because of Feminism. It's not because of the lower importance of religion. It's not a lack of patriotism. People have lots of kids when it is in their interest to do so. Having lots of kids is everyone's economic strategy in an agrarian, pre industrial society. The same applies to industrial economies characterized by low living standards and dominated by substandard jobs. The US is neither of these things. It has high living standards, it doesn't need extra farmhands or kids to hold onto land, and it's people (middle class and below) aren't hoping that their 3 kids help the family's income by dropping out of school and getting into the gig economy.

Seriously it takes two to tango and only the wealthy weirdoes cloning themselves for organ replacement think otherwise.
