Wal-Mart Effect: America Going to Hell in a "Shopping Cart"

Wal-Mart is a business with 1.6 million employees in the United States alone. It does more business than Target, Sears, Kmart, J.C. Penney, Safeway, and Kroger combined. And more than half of all Americans live within 5 miles of a Wal-Mart store. David Gardner talks about the big, big business of Wal-Mart with Charles Fishman, author of The Wal-Mart Effect: How the World's Most Powerful Company Really Works - and How It's Transforming the American Economy.
