Not wanting to have your own kid is one thing (to be clear: a totally reasonable and acceptable thing) but broad anti-natalism is eugenics and it is troubling how pervasive the rhetoric is, even among leftists
no it isn't. rich kids suffer too and it's immoral to force that upon them. treats don't make up for bullying or being assaulted by a priest etc. hell, there's even another angle where raising a kid rich is more likely to make them a sociopathic monster who goes on to harm others and it's probably immoral to create a person who is going to be an Ivy league fratboy.
you don't get to decide for other people whether it is or isn't, and you can't know in advance whether someone will think it's worth the pain and suffering, so it's immoral to force people to live.
