I'm one of said H1B visas, now with a green card. Been here almost exactly 10 years now, after Apple bought my company. I came here for the money and the weather, not for anything else. Frankly I don't think the US society is as "free" as people here seem to believe.
I've mentioned this here before, and (understandably, no-one likes bad news) I tend to get down voted for it, but the simple honest truth of the matter is that the USA isn't geared for looking after people, it's geared towards controlling people. There's things I like about it (the job is great, the weather is excellent, the people (as individuals who I meet day-to-day) are generally wonderful unless driving, the money is still good, I like my house and I met my wife here - my son is dual American/British).
There's things I don't like too, (the militarisation of the police, the lack of any reasonable healthcare, the "I'm alright Jack, screw you" attitude of a *lot* of people - weirdly enough those who often really *aren't* alright, the schooling system, and for lack of any better term, the country's soul). As time passes, and I get older, these seem to be more important. I can't see myself retiring here, and in fact I can't see myself here in another 10 years. That's not the attitude I came to the US with, it's something I've developed while I've been here.
Let's be frank here, I'm not trying to boast, but I'm one of the 'have's - I have a million dollar house (which sounds a lot more impressive than it really is in this neighbourhood) which is almost paid off, I have a high six-figure income, and I've money in the bank. I'm not a "1%er" but I'm up there with the rest... however, even with all of this, I'm not happy with the way the country is going. There's little-to-no safety net for joe public, and seemingly (*both* houses Republican, seriously ?) no desire for that. I think the USA is far closer to oligarchy than democracy, and the long-term trend just looks like it gets worse from here on out.
