To keep the current population stable, every woman needs to have on average two children: one to replace her and one to replace her mate.
If every woman had just one child we’d cut our global population in half in just a few generations.
Capitalism requires exponential growth to make the people at the top richer. This means capitalism is incredibly invested in making sure women have, on average, more than two children each so there is constantly a stream of new and increasing workers and consumers to exploit.
Women not having children is a radical act of defiance against capitalism, and it will not be tolerated en mass.
As birth rates continue to drop, more and more laws limiting a woman’s reproductive freedom will appear.
