Reliance by Wal-Mart workers on public assistance programs in California comes at a cost to the taxpayers of an estimat- ed $86 million annually; this is com- prised of $32 million in health related expenses and $54 million in other assis- tance.
The families of Wal-Mart employees in California utilize an estimated 40 per- cent more in taxpayer-funded health care than the average for families of all large retail employees.
The families of Wal-Mart employees use an estimated 38 percent more in other (non-health care) public assistance pro- grams (such as food stamps, Earned Income Tax Credit, subsidized school lunches, and subsidized housing) than the average for families of all large retail employees.
If other large California retailers adopt- ed Wal-Mart’s wage and benefits stan- dards, it would cost taxpayers an addi- tional $410 million a year in public assis- tance to employees.
