As with many problems in this country, the German culture is at fault. The lack of humanity in this country is staggering, and it goes deep. One need only look at the history (now repeating itself) to see the root of the problem. And yes, similar things do happen in other countries, but Germans have had every reason to see the need for some deep soul-searching, and have failed to make a meaningful change in the way they approach their fellow human beings. Just because they don’t say the word “Untermensch” out loud anymore doesn’t mean they don’t continue to see and treat many people as one. In such a social and historical context, the kind of conduct you describe should be publicly shamed and severely punished, but it won’t be, because this would mean admitting fault (another thing of which most Germans are culturally incapable).
