I've struggled with this a lot. Unfortunately, the question "what's the ideal way to run a society?" is a very different one from "where's the ideal place for me to go right now?".

I'm not from America, but moving there as a high-paid, still-young software developer was a reasonable choice for me. I might advise others in my position to do the same. I'd be less likely to tell people "you should run your country more like America".
