BERKELEY, Calif., Dec. 9 (UPI) -- Six U.S. citizens, all of them tied to retail giant Walmart, are wealthier than the bottom 30 percent of U.S. families, an economist said.
Labor economist Sylvia Allegreto at the University of California, Berkeley, said six relatives of Walmart founders Sam and James Walton were worth $69.7 billion in 2007 and are now worth about $93 billion.
