4 pillars, personal development, psychology, and the South

Pillars:
1. Intrapersonal = What's inside yourself
2. Extrapersonal = Your family, friends, social organizations
3. Vocation/Work
4. Spiritual

So I'm back at my southern home, and on the front porch reflecting on what I feel I'm lacking out here when I'm in the South, and trying to figure out what I'm getting when I'm on the West Coast...what make me happy and feeling more fullfilled...

And I'm looking out over the neighborhood and I'm not seeing people, no one - not a single person. Big yards, bigger houses, single folks riding in their single cars, and I'm suddenly hit by what is lacking here - just PEOPLE, and with the absence of people, most importantly, diversity. There's no people interacting with other people - there is hardly any diverse population base interacting with other diverse populations. The primary socializing places (including diversity) in the South are church, the workplace, and educational institutions (colleges and universities).
I realized that I (and most others?) need their environment to provide the diversity and social interaction within those 4 pillars I mentioned above, to be a complete, wholistic and authentic human being. Aren't we all social creatures? Don't we, developmentally speaking, gain from our (hopefully) richly diverse environment? Isn't passage through the Eriksonian stages highly dependent on a richly diverse social network?

Why do we pay so much attention to the importance of one's environment for infants and children, but not for adults? I think one's social environment, and the effects of it on our development as whole human beings - our attitudes, our values, etc. - is just as important in adulthood as it is for youngsters. Is there diversity in your states/geographical region, in one (or all!) of those 4 Pillar areas?
