"According to a study released last year by Americans for Tax Fairness, Wal-Mart costs American taxpayers $6.2 billion a year in public assistance, including food stamps, Medicaid and subsidized housing. A single Wal-Mart Supercenter costs us between $904,542 and $1.75 million per year as we subsidize their low-wage employees. So what’s the retail giant doing about it? Well, according to a new study Wal-Mart is hiding $76 billion in overseas tax havens to avoid paying the very taxes that allow their employees to eat."
