PS: The point here is NOT that poor people shouldn't have kids, it's that no one should be having kids without having the basics of childcare covered, which necessitates widespread systemic, societal, and economic change so that no parent needs to worry about those basics, and kids can grow up in secure, healthy environments. I completely forgot to mention this when I originally posted it, and that's my bad.
This discussion is hard and society is still not ready for it.
There are absolutely a lot of people that should not be bringing children into this world.
If as a society we're going to say "it's a fundamental right to breed", then we need to fucking fix society so that every child brought into this world is guaranteed the opportunity for success. That means universal public healthcare, universal public education through college, universal access to nutrition...just to start.
Our current system is nothing like that. Once a kid is born today, if their parents suck then they're just fucked, and maybe that kid should have tried being born to better parents.
