Every country has its problems, but among western nations it's an outlier in many ways: the police state, militarisation, surveillance, car dependence, obesity, love of guns, poverty, crime, absolute zero trust in government, culture of suing, lobbying, "democracy", horrendous health-care system etc. For me it was just too much, I couldn't take it so I moved back. It's not that my life was bad or directly affected by most of these things except in a few instances. As a healthy, young, childless engineer I was truly privileged in this kind of society, but I realised I don't want to live in a society where almost everybody else suffers. I always enjoyed American culture, that's one of the reasons why I tried living there in the first place, but I think I can enjoy it better from afar.
