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.

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.

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.

There is tremendous long-term harm when Americans accept ethnic and class balkanization as a de facto fixture of American life. I think that impoverishes our understanding of each other.
