All three activities are hobbies. Things people mostly do when they feel good. It's nothing that gives life a purpose.
In the past a lot of activities connecting different age groups was a job or job-like too. Working on a farm or a family business together. Running a household and childcare together.

This sounds like an inversion of cause and effect.

I find this to be a dire outlook, myself.
I disagree quite strongly. I derive a lot of meaning from these types of activities (in addition to family and friends of course) and zero meaning from my job. It's the narrow focus on work to the exclusion of everything else in life that is the problem - and that's what the comments above highlight.
