David Thornburgh chats with Jeremy Nowak (at right in photo) and Bruce Katz, authors of a new book called "The New Localism." Their thesis: Many American cities have more things going for them than they seem to realize - untapped wealth and assets that could enable them to address many of their challenges. Those cities just have to stop behaving in 20th-century ways, including waiting for federal help that isn't coming anytime soon. Nowak and Katz talk about cities on the rise - yeah, Pittsburgh, we're talking about you - that offer lessons in how to flip this switch.
