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.
Well the main reason you shouldn't have kids is because this world is going down to shit at an accelerating pace.
Between climate collapse, life extinction, resources exhaustion and AI dystopia, where do you see your kids in 20, 30, 40 years? Dead from starvation? Enslaved by oligarchs? Can you see a good life fort them in the horizon?
My kid is a teenager and I already feel like she's living the best of their life already. From their adult life, I can only see it go down.
