Yeah, I'm sure it has changed in some subtle ways. My hometown was very international but most of them came from countries where things were hard and they came over either to protect their wealth or to escape oppression or poverty so they all want to fit in and be as American as possible. They all tell us how shitty their home country was and so it reinforces the idea that the rest of the world is a shithole which as you know is not true.
I feel like the suburbs could be paradise, they just like diversity, open-mindedness and movement and so for me they usually feel like a place to rot. It could change though! I'll see what I can do
