My partner and I (heterosexual relationship) have both independently decided to not have children. Personally, I was raised at first with an abysmal parent, and then by a slightly-better-but-still-not-good parent. Never had money, homeless, abusive, etc.

I don't want to have kids not because they left a bad taste in my mouth (I still love them: they were young, made a mistake, but still tried), but because I never got to experience all the things I wanted to as a child. So my life as a 20/30 something is dedicated to experiencing the world. Finding joy in others, in travels, in food, and in contribution.

That said, if children were ever to be an option, it must be adoption. It is so incredibly selfish to say that the (non-existent) child you might produce with a partner is more deserving of safety, freedom, and a fulfilling life, than an already living person. Granted, adoption is full of its own political and socioeconomic issues.
