1. Enshrine medical rights for women's bodies that allows them to abort pregnancy, and allows doctors to make that decision for them in case of early complication leading to emergency (a conscious woman not at risk would never be forced to accept treatment that would endanger a viable fetus, but a nonviable fetus would never lead to undue risks in a more ideal world than what we live in).

2. We'll start with a democratic system of laws with a philosophy of marginal satisfaction offset by an aversion to suffering taking priority, a good first step would be to simply incentivize education and remaining childless, perhaps with tax credits or guaranteed income welfare.

3. Introducing or reintroducing publicly funded community buildings for education on human reproduction and a distributor of contraceptives.

4. Then, if the majority agrees, we can strip felons of reproduction rights with the outlined and protected by law ability to sue the state in assumption of prejudice based on protected class. Finally, punish people with excessive childbirthing habits, like more than five or six, perhaps with fines and risk of prison time as well as a three strike system for upgrading to felony.

Or at least that is usually how it works. Definitely cannot skip the order in this, though, the education step needs to come first or second and could probably solve this issue alone single-handedly. If we implemented this in reverse order then it would probably just end up in history books thirty years from now as "that time we almost lost entire demographics to racist eugenics" and that would just be awful.
