Your blame is more centered on poor people having more children but that’s not it, even the rich give birth to a lot of children because they feel they can control them and fend for them until they’re of the age of catering for themselves. The problem here is why are people giving birth to more children than what they can be able to handle for themselves? I am from Africa and I have seen a man with more than 200 children and was able to cater for them all, none where nuisance to the society. He was not that super rich but was able to give birth to what he can control and fend for within his means. You can’t stop people from giving birth and where there’s no birth control policy, the result will be more babies in the society. Everyone will love to have a survivor from his gene, will you allow a birth control policy to stop that from happening when it’s your turn to give birth, I think you won’t, so that’s just it.
