>> everything from being able to bike anywhere in Munich, to seeing how well everything is maintained, to how courteous the people are, and even visiting a concentration camp to get a sense that even a good people can fall into depravity
I think a large part of this is the focus on collective good and "do not be evil/selfish" ethos pounded on kids since childhood.
Compare that to the US where kids are taught that individualism is all that matters. Your friends don't matter, family doesn't matter, community doesn't matter, environment doesn't matter etc.
With all its wealth, living in America is like living in a super mario game, constantly avoiding obstructions and hassles.
