The Walmart Effect
No corporation looms as large over the American economy as Walmart. It is both the country’s biggest private employer, known for low pay, and its biggest retailer, known for low prices. In that sense, its dominance represents the triumph of an idea that has guided much of American policy making over the past half century: that cheap consumer prices are the paramount metric of economic health, more important even than low unemployment and high wages. Indeed, Walmart’s many defenders argue that the company is a boon to poor and middle-class families, who save thousands of dollars every year shopping there.
