The real reason they lag behind the U.S. is, they are not free people.
And there are all sorts of hell holes. Some are like most prisons, noisey, violent, people acting up and out, chaos.
And then there are some that are like Super Max prisons. As quiet as a Tomb, and just as safe. And those places are reserved for the worst of the worst. They break harden men.
Sort of like Finland. The Finns even imported and adopted the TANGO, to see if they had any passion. They don't. They are the antithesis of New Orleans. So are the rest you named, with the exception of Hamburg.
I am beginning to think Schubert went to Europe and went native on us.
