Book excerpt: In his trademark straight-talking style, legendary auto executive Lee Iacocca speaks his mind on the most pressing issues facing America today: the shortage of responsible leaders in the business world and in government; the nation's damaged relations with its longtime allies; the challenges presented by the emergence of China and India on the world's economic stage; the decline of the American car business; and the state of the American family. Iacocca shares the lessons he's learned from a lifetime of hard work and adventure, of spectacular successes and stunning defeats, of integrity and grace and good old-fashioned American optimism.
