The Great Recession is more than four years old-and counting. Yet, as Paul Krugman points out in this powerful volley, "Nations rich in resources, talent, and knowledge-all the ingredients for prosperity and a decent standard of living for all-remain in a state of intense pain."

How bad have things gotten? How did we get stuck in what now can only be called a depression? And above all, how do we free ourselves? Krugman pursues these questions with his characteristic lucidity and insight. He has a powerful message for anyone who has suffered over these past four years-a quick, strong recovery is just one step away, if our leaders can find the "intellectual clarity and political will" to end this depression now.
