First it sucked the life out of Main Street businesses, now it's threatening other large retailers like Target and Costco. Wal-Mart, as Charles Stein puts it in his Economic Life column in Sunday's Boston Globe, seems to know no bounds. Even when faced with bad press, the retail behemoth survives, prospers, expands.

The corporation has even inspired websites like Wal-Mart Watch, which documents the corporation's rampant growth and what the site perceives as the resulting damage. Seems strange that a company that raises the ire of so many can find such unabashed success.
