"In 2004, a year in which Wal-Mart reported $9.1 billion in profits, the retailer's California employees collected $86 million in public assistance, according to researchers at the University of California-Berkeley. [...]In 2004, Democratic staffers of the House education and workforce committee calculated that each 200-employee Wal-Mart store costs taxpayers an average of more than $400,000 a year, based on entitlements ranging from energy-assistance grants to Medicaid to food stamps to WIC—the federal program that provides food to low-income women with children."
The numbers are the only thing that's quoted. The conclusion is that if they paid lower wages, the amount of government support to employed people would rise unless those policies were changed also. Government support paid by taxes, including the taxes of those who work at UCBerkeley.
The statement was squarely that it cost the public money to have WalMart in our town - they expressed it as the cost per WalMart.
For example, they could have expressed how much is Saved the public per WalMart. They didn't express it that way. Because it made a more sensationalist article the other way.

And this is with a minimum wage.
