I have a family and am involved in organizing and stuff. Seems pretty common to me.

The people who live in the neighborhood you're describing have most likely bought into the system since they were born. Having a family is just another prescribed step.

Funny side note is that I went to a dsa meeting (yes it sucked) a couple years ago where they claimed to have childcare available. It ended up just being some dude sitting in the back of the room with a puzzle. My kid was the only one there. Perfect example of why people with kids have a hard time getting involved.
