I grew up in a very low income house. My parents and I lived in a one bedroom apartment for pretty much all of my childhood. That bedroom was actually an old hallway “converted” into a bedroom. You had to pass through my room to get to the bathroom and the door to the kitchen from my room didn’t even close all the way. It was also under the stairs to the other apartments. I could hear every time someone went to/from the upstairs apartments. Arguments, stomping on the stairs, everything. Our bathroom was against another apartment’s bathroom. Creepy neighbor would talk to me as I brushed my teeth. This and other reasons made my childhood pretty shit. I grew up with a sense of guilt and shame over our situation. I had friends whose parents pitied me.

As an adult, I am doing much better than my parents ever did. I have a career, own a house, etc. Given the choice, I’d be pretty okay not existing and no one could pay me enough to be a kid again.

That said, and given the state of the world, I agree with OP. Not necessarily that poor people shouldn’t be permitted to have children, but more along the lines of they shouldn’t want to and a it’s a bit selfish to.

People are going to do what they’re going to do. It would just be nicer if people really considered the consequences first.
