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.

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.

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.

I had been hearing on-the-ground buzz that white folks were moving to places like Bend, Oregon, and Coeur d'Alene, Idaho, and St. George, Utah. That led me to discover through census data that these towns were already extremely white and they were becoming, in most cases, even whiter. Statistics could only tell me so much; in order to get to the spirit and essence of it, I had to immerse myself.

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.

I hope we have American-topias.

When well-qualified, upper middle-class blacks or Latinos or Asians move to predominantly white neighborhoods, there's what's called the tipping point. That tipping point is generally 15 percent; at 15 percent you begin to see white flight.
