> The pro-productivity people are more involved parents and family members

I haven't seen this amongst several people I know as pro-productivity. The productivity tends to be hyper-focused on work and side hustles/creative, and family/parental duties seemed to be neglected as a result. But I couldn't find any data on this with a quick search, so it's just conflicting anecdata to your anecdata.

Your other bullet points do align more with my experience, but not this one.
