Sorry if I'm not political correct. I tried. My intent is not to troll or offend people who do shop at Whole Foods. I actually live in San Francisco, 10 feet away from a Whole Foods. I previously lived in Seattle, too. I feel that, compared to other fields such as Finance or law, tech tend to be more self-conscientious and guilty about income inequality.
