I spent a good number of years in Berlin (back when it was called West and East Berlin, depending on which side of the Wall you were on) and the preponderance of snot-nosed punk kids is generally rather high.
Especially in some of the working class districts such as Kreuzberg and NeuKölln where you find the biggest concentration of foreigners, there are a lot of problems with crime, burglary, etc. (Lest I be accused of being a bigot, let it be said for the record that if you wanted to be accosted by a gang, all you had to do was take your ass to Kreuzberg late at night and parade around -- guaranteed you'll find trouble.)
Germany being the socialist country it is and whose citizens readily look on their government as being The Great Benefactor

, it's easy to imagine how Mutti und Vati coddle young Jürgen as he makes his way through life through most of his twenties. After all, the snot doesn't stop flowing until Junior's outta dodge.
