Part of this problem is our societal failure to build enough housing to keep up with the increasing number of people, with a resulting increase in housing costs that has significantly outpaced the median wage. If you can't afford to live on your own, and can't afford housing where the jobs are located, then you're more likely to live with your parents and be unemployed.
The issue is human overpopulation, not our society’s “failure” to destroy the fabric of closely knit communities.
Humans are by far the least efficient life form on this planet, and what little enjoyment most humans get out of life mostly comes down to the integrity of their local communities: their safety, their health, their prosperity. Yet we’ve become so hyperfocused on economic growth that we’ve turned our larger society into a malignant tumor unto Earth, while ironically an increasingly high proportion of humans lead unhappy, unfulfilled lives.
Why do so many people just accept the answer is more growth? Until we can master interstellar travel, we have to contend with finite physical resources.
