I work in tech, work reasonable hours, live in Oakland, and do all those things. I also have many neighbors who work in tech and outside tech (healthcare, law, skilled trades) and work reasonable hours, and do all those things.

I think doing all those things is a function of whether someone is in a particular industry. It is a function of whether one has a desire to be involved in one's community.

Having kids is a stronger predictor of community involvement if you are looking for one.
