Here is a popular magazine treatment of the debate between New Urbanism and Richard Florida against opponents and Joel Kotkin:

Many cities, in consequence, have become “Floridian,” with “loft districts” rising from industrial ashes in Cleveland and Raleigh, hipster enclaves in Chattanooga, a gayborhood in Philadelphia, reclaimed waterfronts in Baltimore and Minneapolis. Much of this work preceded Florida—but there was socialism before Lenin, too. Florida gave the New Urbanists the vision they wanted of themselves, as saviors of the American city emptied by suburban sprawl, champions of creativity and ingenuity who were going to make Indianapolis the Paris of the 22nd century.

But any intellectual movement must encounter a backlash, and the one to the New Urbanism is only growing, in part because it’s now mature enough for us to see its effects. On the face of it, the New Urbanism is very pretty: Court Street in Brooklyn looks splendid, as does San Francisco’s Valencia Street. The aforementioned travel section of The New York Times has a column, called “Surfacing,” that frequently resorts to profiling some forlorn, blighted neighborhood suddenly graced by taxidermy shops that double as yoga studios. I am, as a matter of fact, writing this from a Whole Foods in West Berkeley, California, a formerly industrial district that was recently “Surfaced” in the Times. The coffee I am drinking was roasted about 20 feet away from my Apple laptop. How’s that for local?

Problem is, surfacing is usually whitening: Gentrification by any other name would taste as hoppy, with the same notes of citrus peel. There is really only one strike against the New Urbanism, but it’s a strike thrown by Nolan Ryan: It turns cities into playgrounds for moneyed, childless whites while pushing out the poor, the working-class, immigrants, seniors and anyone else not plugged into “the knowledge economy.” Right around the time that Michael Bloomberg was remaking Manhattan as a hive for stateless billionaires, I saw a slogan that captured perfectly the new glimmer of the city: “New York: If you can make it here, you probably have a trust fund.”

You could accuse me of writing a faux-populist diatribe, but the numbers are on my side this time around. Jed Kolko, a Harvard-trained economist who was, until recently, the chief of analytics for Trulia, has found that from 2000 to 2014, more Americans moved out of urban centers than into them. Using data from the U.S. Census, he concluded, in a recent post on his blog: “While well-educated, higher-income young adults have become much more likely to live in dense urban neighborhoods, most demographic groups have been left out of the urban revival.” The people who continue to move to cities, he concludes, are “increasingly young, rich, childless, and white.” These are the creatives, the hipsters, the pioneers, who fled the countryside for the big city, where cultures would clash and ideas foment. But all they did is turn Bedford-Stuyvesant into Minnetonka.

So what? I posed this question to Joel Kotkin, an urbanist and demographer based in that decidedly suburban setting of Orange County, California. Author of the forthcoming The Human City: Urbanism for the Rest of Us, Kotkin defends the suburbs, which is nearly as radical as an evolutionary biologist defending creationism. Kotkin argues that suburbs are where middle-class families want to live, and middle-class families are, as he told me in a recent phone conversation, “the bedrock of the Republic.” A city hostile to the middle class is, in Kotkin’s view, a sea hostile to fish.

What is the answer to this debate, which like many others, have become politicized (Republican visions of small towns and suburbs and Democratic visions of thriving cities)? Could both sides have some merit to their arguments – New Urbanists regarding aesthetics and community life and Kotkin et al. with American’s continued interest in suburbia? One possible solution is to introduce more New Urbanist developments and communities in suburbs. This would allow people to have their suburban life but at higher densities and with planning that might encourage more street life.

At the same time, neither New Urbanists or Kotkin really address issues of race and ethnicity in the United States. Both do so indirectly, suggesting that their models offer better options for non-whites. But, what if the larger issue was really residential segregation, which can occur in New Urbanist communities as well as in suburbs?

Additionally, I cannot imagine too many city or suburban leaders would turn down or discourage wealthy residents moving to their community.
