I would not mind working in USA for a year or two, for a change of scenery, so to speak. But apart from a high level of life (which is probably not so high for new immigrants) and beautiful nature I don't find it appealing, and I would not like to immigrate "for life".
I think I would be perpetually annoyed, if I did, because there are dozens of things that I do not particularly like: system of education, ratting each other out at the workplace, nosy neighbours, sport scolarships, political correctness, fixation on "freedom" and liberating the world, compulsory smiles, fart jokes and many other things.
Learning a new language from scratch? Seems scary.
