In many of these cases it seems like having kids may have been an ill-advised life choice. Having kids is always a choice not a right.
so only the rich should reproduce? absolutely disgusting mindset. nobody chooses a life of poverty, and the overwhelming inequality of our current society both perpetuates and exacerbates it.
Having sex is a choice, there are risks involved, one of them is pregnancy.
Many people who aren't considered "rich" can raise children and be economically comfortable.
I'd encourage you to ask someone who grew up in poverty or with uneducated parents (who accidentally had children or decided to have four children knowing they couldn't afford it) if they'd willingly put a child through what they went through growing up and I think my point would be crystal clear.
