In Palaces for the People, Eric Klinenberg suggests a way forward. He believes that the future of democratic societies rests not simply on shared values but on shared spaces: the libraries, synagogues, and parks where crucial, sometimes life-saving connections, are formed. These are places where people gather, making friends across group lines and strengthening the entire community. Klinenberg calls this the “social infrastructure”: When it is strong, neighborhoods flourish; when it is neglected, as it has been in recent years, families and individuals must fend for themselves.

Thirty years after its publication, The Death and Life of Great American Cities was described by The New York Times as "perhaps the most influential single work in the history of town planning....[It] can also be seen in a much larger context. It is first of all a work of literature; the descriptions of street life as a kind of ballet and the bitingly satiric account of traditional planning theory can still be read for pleasure even by those who long ago absorbed and appropriated the book's arguments."

In recent years the young, educated, and affluent have surged back into cities, reversing decades of suburban flight and urban decline. And yet all is not well, Richard Florida argues in The New Urban Crisis. Florida demonstrates how the same forces that power the growth of the world's superstar cities also generate their vexing challenges: gentrification, unaffordability, segregation, and inequality.

The term gentrification has become a buzzword to describe the changes in urban neighborhoods across the country, but we don't realize just how threatening it is. It means more than the arrival of trendy shops, much-maligned hipsters, and expensive lattes. The very future of American cities as vibrant, equitable spaces hangs in the balance. How to Kill a City takes listeners from the kitchen tables of hurting families who can no longer afford their homes to the corporate boardrooms and political backrooms where destructive housing policies are devised.

Jeff Speck has dedicated his career to determining what makes cities thrive. And he has boiled it down to one key factor: walkability. The very idea of a modern metropolis evokes visions of bustling sidewalks, vital mass transit, and a vibrant, pedestrian-friendly urban core. But in the typical American city, the car is still king, and downtown is a place that’s easy to drive to but often not worth arriving at. Making walkability happen is relatively easy and cheap; seeing exactly what needs to be done is the trick.
