I don't want to live in a monoculture of any kind. I don't want to live in a wealthy monoculture, a black monoculture. I don't want to live in an elitist, progressive monoculture.

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.

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.

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.

If I were an immigrant Latino not born in the US, I could not have written Searching for Whitopia: An Improbably Journey to the Heart of America book. And that is because many of the Whitopians would not have been comfortable talking about their views on immigration, talking about their views on taxes. And they wouldn't have spilled to me the new script on race and poverty as they did.
