That's true that it would be good for more access to birth control, but this is a confusing statement because you benefit economically and socially from each new kid that is born and raised. If child care is socialized, it means that the kids are going to be better taken care of versus the mother is impoverished and (a) doesn't work and stays poor or (b) does work and they aren't taken care of properly.

I guess you can make a malthusian argument that the poors will just replicate indefinitely as resources are made available, but I don't think that's believable at all. You should be focused on making sure those future citizens are properly educated and socialized.
