The problem with the “snobbery” argument is that we don’t hear limousine liberals saying anything unpleasant about Costco or Home-Depot or other big retailers that have pretty much the same customer base as Wal-Mart does. I submit that there is one and only one difference that matters: Wal-Mart has resisted unionization. That is what makes it the Great Satan in the eyes of the moguls of Big Labor. And whatever the moguls of Big Labor dislike, politicians who court their favor must also dislike.
