I was surprised by how forces in the community could mobilize against a community changing. There were many examples of this. In St. George, members of the Latino community proposed having a "Dixie Fiesta." The resistance to that surprised me.

People would say, "You know, Rich, it's nature. Birds of a feather flock together." I have to point out to them that, no, that's not the case.

The interesting thing about Georgia is, Atlanta is teeming with middle-class black people and black people with money - and yet there is still segregation.

It's the texture of New York that people miss by filming elsewhere. There are layers and layers of character - even in the pavement - that you can't get anywhere else. And the speed that the people move. It's so different from other places.

Louisville, Colorado, which was just voted by CNN and Money magazine as the best place to live, is a veritable Whitopia that is unaffected by the housing crisis and even the severe recession. You look at the best places to live, according to Money's 2009 list, and 9 of the 10 are Whitopias.

The reason our country looks the way it does is through social engineering that distinctly benefits suburban communities, exurban communities, and often white residents. And we are socially engineered in such a way as to, often unconsciously and unintentionally, but sometimes intentionally, perpetuate this divisive inequality.

I concede that segregation can allay social tensions immediately, but it further debilitates us in the long run.
