Needing immigration to make up for plummeting birth rates in the US will be a challenge in the current political climate.
Having kids is expensive and for many people of reproductive age there's the additional concern of bringing a child into a world in crisis. I believe that all these problems are technically solvable but are not politically palatable.
The simplest thing that we could do would be to subsidize childcare so that the biggest economic hurdle would be addressed. But again, that would be dismissed as socialism and would be a non-starter today.
