It was an urbanist’s nightmare. On Feb. 1, a teenager was shot dead in the middle of a popular art gallery walk and street fair in Oakland, Calif. — a town that highlights exactly what a city wins and loses when it attracts a huge influx of the vaunted “creative class.”

In a story that has implications for Detroit, with its growing creative class, Susie Cagle reports on Grist.org that the shooting highlighted a stark reality: The creative class is remaking Oakland in its own image, but the “urban renaissance” isn’t benefitting everyone. The neighborhood where Campbell was killed has new condos and galleries — and a median household income of less than $22,000.

By the urbanist creative-class metric, Oakland is winning. It’s a top city for urban farmers, local organic gourmet food snobs (love you, food snobs!), cyclists, and art-lovers. It’s home to a growing number of imported young makers, tech start-ups, and rising artists, in large part because of its close proximity to San Francisco and Silicon Valley. At the same time, about 13 percent of Oakland residents are unemployed, and the city still has one of the highest murder rates in the nation, especially for teens.

For years, Richard Florida and other urban life pundits have espoused the creative class as the secret to city success. When the creative class wins, their logic goes, we all win. Gentrification has essentially become America’s favored urban redevelopment strategy.

Florida has acknowledged that the rise of the creative class can exacerbate urban class divides, but his new research highlights just how big those divides can be.
