At various points throughout human history it was also common for people to forage/hunt/grow their own food, too.

I resonate with the rest of your post - I do think having a connection to society is vital, and I also think that the US has become too much of a me-first, get-ahead-at-all-costs hustle culture that devalues social bonds. But I see people still forming very deep cultural identities.

I also agree with you that pride in one's accomplishments and a sense of purpose is important and home ownership is ONE way to achieve that - to have control over at least that facet of your life.

But it's far from the only one.
