In That Used to Be Us, Thomas L. Friedman and Michael Mandelbaum analyze the four major challenges we face as a country---globalization, the revolution in information technology, chronic deficits, and our pattern of energy consumption---and spell out what we need to do now to preserve American power in the world. The end of the Cold War blinded the nation to the need to address these issues seriously, and China's educational successes, industrial might, and technological prowess in many ways remind us of a time when "that used to be us." But Friedman and Mandelbaum show how America's history, when properly understood, offers a five-part formula for prosperity that will enable us to cope successfully with the challenges we face. That Used to Be Us is both a searching exploration of the American condition today and a rousing manifesto for American renewal.
