Only if we had better methods of allowing social mobility and selecting the best among us that wouldnt involve which family you came from. /s

On a more serious note I really believe that only the "poor hustlers" strata of society is not having kids, i.e couples that have good jobs but would be poor if any of them stopped working, so they have a dog for now and pretend they will have kids after they're 40.

If you go up on the ladder you probably don't have the same growth problem, take N=1 Ellon Musk with 7 kids as example.

Reminds me of how having real animals on Blade Runner was a privilege of the ultra rich :).
