Ok, maybe not quite, but that they're still being asses.
I'm always fascinated by how certain people always seem to think they're on the right side in a moral fight, but they never actually are. How, exactly, does one make a case for absolute morality forbidding this practice, even though it clearly is meant to harm and hold back individual workers to the benefit of people in a thriving company that are already obnoxiously rich?
Absolute morality == failure.
Wal-Mart Supporters == failure.
The last thing I bought there was one of their loss-leader products, a $73 air conditioning unit that they tried to hide so you'd buy one of the more expensive models. I've always wondered how long it would be until my refusal to shop at Wal-Mart resulted in an "Anti-Economic Terrorism" bill that required that at least x% of my income be used at Wal-Mart and related megastores on a yearly basis. I should start up a pool so people can wager on it.
