KC builds on Michael Sansolo's column this morning by focusing on a smart move by Whole Foods - teaming up with Teachable, an online education platform, to develop a course called Home Ec 365, designed to help people be more effective in the supermarket and the kitchen. Which will make them more self-sufficient. If supermarkets take advantage of this moment, KC argues, it will help them know and serve their customers better. And he has some suggestions about the kinds of questions they ought to be asking.
