My life in the US was definitely not easy, and much less easy than my life in the UK. I must have had a far different experience than a lot of you, because for me, living in the US meant constant worry about making ends meet (teachers don't get paid much no matter where they live), paying bills, getting sick (no insurance so no medical treatment), transport (no car), yet having to drive everywhere because the distances were unwalkable, plus people treated you like a freak if you walked anywhere, pressure to achieve, judgement if you were not ambitious, pressure to justify your expensive education by getting a high paying job, judgement if you didn't make much money, etc etc etc. I find the UK far easier in all respects, and even though I don't earn very much, proportionally I'm making as much as I could expect at a similar job in the US, only here it's more fulfilling and more dependable. I can't even begin to gauge how much better and happier I feel here than I ever did there.
Although I have to say that of all the places I've lived, Japan was by far the easiest from a financial standpoint, in terms of income versus cost of living, plus it's safe, clean, organised, convenient, and also historical and interesting. It's like the best of the UK and the best of the US together. On the other hand, the language and the culture are both extremely difficult to penetrate, so in that respect it wasn't easy at all. Still, if for some reason I ever had to leave the UK, I wouldn't go back to the US, I'd go back to Japan.
