Fishman shops at Wal-Mart and has obvious affection for its price-cutting, hard-nosed ethos. He also understands that the story of Wal-Mart is really the story of the transformation of the American economy over the past 20 years. He's careful to present the consumer benefits of Wal-Mart's staggering growth and to place Wal-Mart in the larger context of globalization and the rise of mega-corporations. But he also presents the case against Wal-Mart in arresting detail, and his carefully balanced approach only makes the downside of Wal-Mart's market dominance more vivid. Through interviews with former Wal-Mart insiders and current suppliers, Fishman puts readers inside the company's penny-pinching mindset and shows how Wal-Mart's mania to reduce prices has driven suppliers into bankruptcy and sent factory jobs overseas. He surveys the research on Wal-Mart's effects on local retailers, details the environmental impact of its farm-raised salmon and exposes the abuse of workers in a supplier's Bangladesh factory. In Fishman's view, the "Wal-Mart effect" is double-edged: consumers benefit from lower prices, even if they don't shop at Wal-Mart, but Wal-Mart has the power of life and death over its suppliers. Wal-Mart, he suggests, is too big to be subject to market forces or traditional rules. In the end, Fishman sees Wal-Mart as neither good nor evil, but simply a fact of modern life that can barely be comprehended, let alone controlled.
