I lived there for a few years (NJ, NYC, Boston and elsewhere in Mass), was planning to do a doctorate at Brown, and was on a pathway to permanent residency, but I had to drop everything to go home at no notice after a family member was in a car crash, and I realised I didn't want to spend any more time living in the US. I moved to the UK instead and spent years living there.
I slept with nice American men and not so nice ones. I realised I only experienced one small corner of an enormous country. I was fascinated by how much space there was, and wildlife that could kill you, in rural Vermont and Maine. I'd never encountered bears before, far less seeing bear footprints on the front porch after snowfall. I still go there for work periodically. Sometime I will take a road trip and see some parts of the country I've never been to. But no, it's never occurred to me to want to live there again, and leaving was the right decision for me. There are things that charm me, sure, but a lot that didn't.
When I was a student cleaning rooms in a hotel, I was very aware of how hard the lives of even the white collar workers (Accounts and Reservations people) seemed -- I remember one nice woman who worked in Reservations 8 till 5, went home, had dinner with her husband and kids and then went straight to a GP surgery call centre where she worked overnight as an out of hours call handler, sleeping when she could between calls. Then she went home, took a shower, had breakfast with her family, and went straight to work in the hotel. All 'to put the kids through college.' And she wasn't unusual.
