Wal-Mart: Stupid or Arrogant?

Wal-Mart Chief Defends Closing Unionized Store (washingtonpost.com)

Wal-Mart Chairman H. Lee Scott on his company's bully boy tactics in Chicago:

"Our size causes us, when we do something inappropriate, which is usually done out of stupidity, to come across as being done out of arrogance. And people just won't stand arrogance."

Now Wal-Mart has created an uproar by shutting down its only union shop in Quebec instead of agreeing to arbitration. Stupid or arrogant?
