Wal-Mart employs over 1.6 million people and saves consumers $20 billion per year. However, they are accused of monopolistic practices that put other businesses out of business and exploiting workers with low wages and poor working conditions. Their environmental policies are also criticized for polluting local water sources. Workers in foreign factories that produce goods for Wal-Mart report being forced to work long hours in extreme conditions and being paid very low wages, while giving inspectors false information about pay and conditions. Crime in Wal-Mart parking lots is also a major issue.
