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.

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.

Problem with segregation isn't that people can't live in peaceful harmony singing "Kumbaya" - although that wouldn't be bad. The problem is that many of these Whitopian communities are taking state, local, and federal resources with them.

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.

By 2042, whites will no longer be the American majority.
