While I don't share your sense of nature/nurture as being simple, I think I understand your perspective. I would never imagine taking all credit or all blame for my own children, but there is something to say for supportive vs dysfunctional families. Still, some very good parents end up with children who self-destruct, and some really bad parents end up with children who put themselves through Harvard.

What I would find more meaningful is comprehensive sexuality education (including parent tips), free access to birth control, community support structures for struggling families, and funding for preschools. It's simple to privatize the responsibilities of family, but we all have a public stake in supporting the socialization and healthy development of young people who do not choose their families.

My children wouldn't be the people they are without the benefits this community has provided them. I'd like to take credit for them, but I'd be lying to myself.
