The Costco Challenge: An Alternative to Wal-Martization?

Hmmm, fancy that, by paying their workers a fair living wage Costco actually saves money by retaining more effecient workers, and not having to constantly recruit, interview, test and train new employees. Nice to see some positive numbers behind the benefits of actually conducting business with integrety and some sense of moral good. Or maybe there's no good intent, but they have figured out a more sustainable business model that benefits the employees as a side effect.
