It's true that any given German grocery store has fewer choices than any given US one, but extrapolating that to "there are no choices" is absurd. Germany has more choices of grocery store, and in both countries if you really want good meat you go to a real butcher (definitely not Whole Foods) anyway.
Your comment about universities must be a joke, or your social circle lacks any kind of discrminating ability. I've had multiple conversations with a dozen Germans about exactly this topic in the past month regarding our recruitment/hiring practices.
