Not only did they just get a guy from Wal-Mart, they got THE guy who changed Wal-Mart from the way it was when Sam Walton ran it. Sam ran a "Sell it cheap, yes, but let's source American as much as possible / Loyal customers are worth more than bargain hunters" model. I remember a few instances where Sam bought into factories so that they could keep buying from American production (even if some were foreign-based companies, the production was still in the USA).
David Porter is responsible for everything negative you think of when you think of Wal-Mart. Low price first, customer service costs money, fuck loyalty, stockholders not customers, etc.
