The Wal-Mart Response

Via Tyler Cowen at Marginal Revolution, comes this story in the Washington Post about the incredible action taken by Wal-Mart to aid victims of Hurricane Katrina:

In Brookhaven, Miss., for example, where Wal-Mart operates a vast distribution center, the company had 45 trucks full of goods loaded and ready for delivery before Katrina made landfall. (emphasis added)

Many will question their motives (i.e. corporate image, etc...), but isn't the end result what really matters in this case?
