One gets the feeling that it's a more egalitarian city than other US metro areas. I didn't feel like it was that racist of a city, certainly nothing compared to Pittsburgh, where I now live.
And there are very few establishments that are designed exclusively for the wealthy. The Frontier restaurant near UNM is a great example of what I'm talking about. You would regularly see news anchors, professors, doctors, etc. dining there in the same room as people who were homeless.
