Various governments and supermarket unions are working hard to keep Wal-Mart out of the Washington, D.C. area:

Giant Foods, Safeway and Shoppers Food control 55 percent of the local grocery market, and their union is relying on its strong political ties and sympathetic shoppers to stop Wal-Mart’s expansion. At stake, the union says, is the future of more than 20,000 supermarket jobs that offer a middle-class lifestyle to the region’s unskilled workers.

Yeah, we can’t have people actually earning their way to “a middle-class lifestyle.”
