As fertility rates are held down longer by individual choices, raising them back up becomes harder. Countries have spent hundreds of billions of dollars attempting with little to show for it. ~71% of the world’s population now lives in countries with birth rates below the replacement level needed to maintain population size (as of this comment).

Therefore, my mental model is:

1. It would take time to attempt to pass policy to not provide welfare or social safety nets to people who don't have children. The fight would be long, if at all successful.

2. During this window of time, say 3, 5, 10 years to accomplish this, the fertility rate globally will continue to decline. This will further reinforce the fertility trajectory.

3. You succeed and now women have to have children to be eligible for a pension or its equivilent. You will, in my opinion, be faced with revolt from a significant portion of the population impacted by this decision. Humans who are having their autonomy and agency challenged will seek and implement, for lack of a better term, defenses and countermeasures. Memento mori.

> This is a hard argument to make, I typically lean far more collectivist, and don't like the conclusions this leads me to in terms of what incentives will move the needle vs. not, but I'm struggling to see other paths that sufficiently impact the incentive structure.

No paths exist to sufficiently impact the incentive structure, based on all available evidence. No changes will occur to the fertility curve trajectory we are on. Like the momentum of climate change, the best you can do is prepare and adapt for a future that will arrive and that you have no control over.

An analogy to attempting to coerce women to have children that is my "go to" example is Romania's Decree 770, instituted by the communist government of Romanian dictator Nicolae Ceaușescu, restricting abortion and contraception to grow the nation's population. It led to immense suffering of unwanted children left in orphanages by parents who could not or did not want to care for them. Luckily, these events led to the public execution of the dictator mentioned during the Romanian Revolution.
