It never ceases to disappoint me, that Germans have a complete lack of an ability to appreciate the comedic potential of Hitler and the Nazis like we Brits do.
The level of self imposed guilt and repression is no way to deal with any traumatic past event, whether it be on a personal level or on a societal level. Whilst most Germans will tell you that this is a good thing because it ensures that such a movement can never happen again in Germany, I suspect the opposite may more likely be the case. Somewhere buried deep in the German psyche, is a knowledge that the eruption of the Nazi movement into mainstream German life happened for a reason, and so long as this cannot be acknowledged and the spiritual scars truly healed, then this conflict within the individual and collective unconscious will seek to resolve itself and will knock persistently against the doors of the conscious mind, perhaps one day breaking out and overcompensating into a re-embracement of much of the emotional and mental expression that was embodied in the Nazi ideology. This might especially be the case should the German economy suffer in the same way that the southern Med countries economies are going to suffer which will erode the material glue which is presently all that holds Western civilisation together.
Edit:
Having thought more about the matter. Perhaps one of the effects of the ever increasing multiculturalism of Germany, is that the effects of the collective spiritual volatility of the longer established native Germans, will be diluted. As people who haven't inherited the same spiritual tensions will not relate and react as readily to any outward expression of such tensions. Thus acting as a kind of resistance to any mass cultural expression (positive or negative) that might be triggered from within the native collective unconscious. Having said that, If the different cultures in Germany remain as segregated as say the Turks are from the native Germans, then obviously this could have a very negative effect on what may transpire once the wealth stops rolling in. This applies not to Germany, but perhaps the whole of Western Europe. I sometimes wonder whether the Muslim minorities that are being allowed to establish themselves throughout the West are not being set up as the scapegoats for the outbreak of social angst which may be yet to come.
