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

In the pioneer West Whitopias, immigration tended to be the dominant social and racial issue. In Forsyth County, Georgia, immigration is still an issue, but because you have that complicated history of the Trail of Tears and slavery and Jim Crow, the Whitopia has a different flavor.

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.

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.

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.

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.

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 always say that you should remake flops, not hits.

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.

With growing and intermixed minority populations, our democracy can not work optimally unless all people are integrated as full and equal members, and I think our collective freedom requires that.

I hope we have American-topias.

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

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.
