On the one hand, we say we want more mobility for economic prosperity. On the other hand, we lament the decline in social fabric and support systems that prevent loneliness and enable young people to have kids by said mobility. We eventually must come to terms with the fact that we can't have it both ways.
We can't have unlimited amounts of both. We can have some of both at the same time, though. You can move and make new friends, and keep some of the old, and have some social fabric and some mobility. You can't have as much social fabric as if you never moved, though.
I think we can definitely have more of both than what we currently have, the primary issue today is mostly political dragons standing in the way of some reasonable economic fine tuning.
So like every Bay area tech worker jumping on a bus at 8:00am until leaving the office after 6pm. And those few of us who don't want that are pressured by managers happy unleash a PIP.
You're making my point. People, including my grandfather, are moving because they put their career above people, family, friends, and relationships. And when they get there, they're still themselves and the grass isn't greener, but they get a Lexus rather than a Camry -- woop-de-doo.
