Richard Frorida's latest book, The New Urban Crisis, represents the culmination of this long mea culpa. Though he stops just short of saying it, he all but admits that he was wrong. He argues that the creative classes have grabbed hold of many of the world’s great cities and choked them to death. As a result, the fifty largest metropolitan areas house just 7 percent of the world’s population but generate 40 percent of its growth. These “superstar” cities are becoming gated communities, their vibrancy replaced with deracinated streets full of Airbnbs and empty summer homes. Meanwhile, drug addiction and gang violence have spread to the suburbs. “Much more than a crisis of cities,” he writes, “the New Urban Crisis is the central crisis of our time” — “a crisis of the suburbs, of urbanization itself and of contemporary capitalism writ large.”

The author offers both—specific solutions like more affordable housing, more investment in infrastructure, and higher pay for service jobs—and vague ones—“engage in a global effort to build stronger, more prosperous cities in rapidly urbanizing parts of the world” and “empower communities and enable local leaders to strengthen their own economies.”
