This doesn't seem sustainable, to me. Just basic evolution. As long as some subpopulation has a birth rate above replacement rate, that subpopulation will grow, until the total birth rate at least returns to replacement.
I feel like human culture has still not reached a steady state after the invention of birth control. I don't know what will happen per se, but it seems like the world of the future will have to be more encouraging of parenthood, in some way, than the world of the present. I hope it is a way that is consistent with the model of a modern free Western democracy.
