Political discussion while hitch hiking

Just outside Wurzburg we got a lift all the way to Munich with a very interesting student (28 years) who planned on immigrating to Spain and getting involved in politics. He spoke good English and we cross questioned him about present feelings about WWII. We were both surprised to hear that the Eastern boarder of Germany is still a contentious issue and some still feel that parts of Poland and Chekoslovakia belong to Germany. Also 60% of Germans live alone or are single and the German mentality is one of mere material survival. This guy believes that it is forever the duty of Germany to be an example in history to prevent such a thing from ever happening again. He thinks the sensitivity/tension of the subject will prevent another German Hitler from ever coming to the fore. The issue of whether berlin will ever be the capital again is also a topical subject.
