In Sam We Trust is the true, unvarnished story of the Wal-Mart colossus at work, and of how its remarkable success illustrates the glory as well as the underbelly of American capitalism. A flinty workaholic obsessed with his stores at the expense of his personal life, Walton established the ruthlessly efficient strategy that enabled Wal-Mart to surpass Sears, outsmart Kmart, and crush small-town mom-and-pop stores. Bob Ortega, a veteran reporter who covered Wal-Mart extensively for The Wall Street Journal, has written an illuminating and authoritative account of the world's most powerful store, and of how Sam Walton's way of thinking is transforming America's -- and the world's -- business practices, workplaces, and communities.
