The article mentioned only briefly the protests at many Wal-Marts over working conditions. One protester I saw interviewed on TV said she couldn't make it even with the rent subsidy she receives. My niece works at Wal-Mart full time and qualifies for food stamps and Medicaid for her children.
Wal-Mart makes the money while we taxpayers help feed and house its employees. This is corporate welfare, not capitalism. Without taxpayer subsidies, Wal-Mart would have far fewer employees.
