That piece seems wildly insincere and misses the point, as does anything that just compares Wal Mart to Costco. Usually what people compare is Sam's Club to Costco. Sam's Club is the direct Costco competitor that is also owned by the Waltons. Of course Wal Mart is a different beast than Costco, everybody knows that. But that doesn't mean that Wal Mart couldn't treat its employees better. If anything the facts of McArdle's piece prove that point. (They are making plenty of profit, a lot of which could be reinvested in employees.)
