Well, I was already inclined to call Whole Foods "Whole Paycheck" but did occasionally go there to either look at or buy things that are difficult to find elsewhere, usually personal care products. No more.
I'll shop elsewhere, thanks...
ETA: The blog linked is heavily left-leaning, I might add and not particularly detail-heavy in their discussion of Mackey's editorial. While Mackey makes a few good points, the majority of his suggestions would do very, very little to address the health care crisis in the US and, in fact may well make a number of things worse (in particular, his suggestion that regulations on what insurance companies must cover should be removed seems especially ill-advised). My further research into the CEO of Whole Foods has made increasingly less inclined to do business with his company - I do not care for acolytes of Ayn Rand. I care less for people who create alter-egos to make message board posts slamming their competition, if only because it seems like a pretty stupid thing for someone who is supposed to be responsible for an entire corporation to do, but what the hell do I know - they did eventually buy out Wild Oats. I also don't particularly care for the misleading use of terms like "natural" and "organic" in labeling and advertising when there exists no objective standard for what those terms actually mean, but Mackey and Whole Foods are definitely not the first or the only entities guilty of that.
In any case, I'm sure Mackey and his fellow libertarians will be entirely unhurt by my decision to avoid Whole Foods, especially since it is a choice the upholds the very principles of the free market.
