Anti-Walmart protesters gather on the steps of City Hall in New York, February 3, 2011. Wal-Mart's lengthy struggle to open in New York City has hit fresh problems -- a controversial report that said America's biggest discounter does not just sell cheap, it makes neighborhoods poorer. The report concludes that Wal-Mart , the biggest U.S. private employer, kills jobs rather than creates them, drives down wages and is a tax burden because it does not give health and other benefits to many part-time employees, leaving a burden on Medicaid and other public programs.
