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.
Does any other jurisdiction ban one's company from leaving? None that I'm aware of.
Just losing that future option value is sufficient to deem such a move insane regardless of original jurisdiction - unless for some reason there is zero other option.
Not just due to this, but the more I read and learn about the US, the more that is exposed about the US, the less I now want to live there.
