Is there any other city in the USA that compares to NYC in terms of cosmopolitan nature, sophistication and internationality? I think not. Sure you are right. Everything outside of NYC in New York State tends to be white trash. People from San Francisco aren't white trash either...
Well I can agree with you on SF.. unless I consider that most of that city is another form of garbage.
I would have to say that San Diego, Chicago, Boston, and maybe a couple others are quite well rounded as well. And I can defend white trash in the area that out of all the low income demographics whites have the lowest crime rate.
They may be poor but at least they behave.
