Julian Sanchez links to lots of interesting Wal-Mart related stuff here. For instance he (while giving a tip of the hat to Byron York) notes the following about the new documentary, Wal-Mart: The High Cost of Low Price:
[T]he heartwarming opening scene is basically a con: You’re introduced to the owners of a mom and pop store putatively driven out of business by a new Wal-Mart… except it turns out that the place closed months before the Wal-Mart opened, and (as the owner himself describes it) for reasons having nothing to do with Sam Walton’s latest borg cube.
