This is an article from the Motley Fool ... John Mackey is on the board and they still put out an article saying that WFM is pretty much doomed.
"Whole Foods simply doesn't have a sustainable competitive advantage. In my experience, there's nothing more important to the success of an investment than the sustainable competitive advantages of the underlying company. I have the utmost respect for what Whole Foods has done for our country. We eat better food now, and are much more educated about where it comes from, thanks to Whole Foods. Unfortunately, the company did such a good job of doing this -- and making so much cash from it -- that the competition caught on. And when it did, there was nothing left for Whole Foods to offer that others couldn't. That's a great thing for Americans looking to eat a better diet, but not so great for Whole Foods shareholders."
