Hmm, I don't know if it's exceptionally nice, but it's definitely nice. I've also visited NYC. Didn't feel unsafe at any point, though of course I didn't wander too far out. Walked a bunch around Manhattan and Brooklyn, took the subway a couple of times.

I don't think the US is as bad (in this respect) as media would have you believe. Having grown up in a relatively large dwindling industrial city in the Midwest, visited Chicago very regularly for a time, lived in the southeast, and now in one of the cities often cited as 'crime ridden', I know one person who was mugged and they knew their assailants and it was in my hometown which no one would recognize.

I have friends from St. Louis and Detroit, some of the percieved 'most dangerous' cities here. While they recommend caution or street sense when I visit, I haven't experienced anything but kindness or indifference from strangers. On the other hand, one of my friends was hit and killed by a car in Detroit, and when I left town in the southeast once, saw a bunch of white power banners on someone's house, which is kinda a promise of crime.

None of this is to say I think the US is better than Brazil or Estonia or anywhere else, I've got endless criticism for this country. I mean that the crime reported on is usually exaggerated, and the likelyhood of experiencing the crime that does happen increases as the money you have decreases.

And not to make this even longer, but the people with the means to move to another state much less another country are the wealthy. The poor, who are the ones who might benefit most from moving, are unable to, trapped in the cycle here.
