What does a feminist model for society look like reproductively?
Up to now we have largely been in a "state of nature" wherein people generally had however many children that could survive.
Human societies have essentially had to live in a state of nature and all patriarchal models for society dealt in that reality and created societies that took the state of nature as a given reproductively.
China is the only example I know of with a truly patriachal reproduction model, wherein the state instituted a one child policy and enforced it.
But for most of the first world we now exist in a largely matriarchal model for reproduction.
Meaning (for the most part) women control reproduction in nearly the entire developed world.
Considering this reality, is there feminist writing/theory/implementation for matriarchal models based around this?
I see a lot of males talking about this stuff, but realistically men don't have the final say, meaning society almost intrinsically have to look to feminists for the answer here.
Starting anywhere else kinda puts the cart before the horse.
TLDR: Matriarchal reproductive control is already a reality in the developed world generally, what are feminist solutions for things like pension systems, school management, elder care etc. In worlds where the decision is made to have fewer children?
