Don't waste your energy, the same lack of knowledge Tsingtao displayed about Greece in various other threads, he displays regarding Germany. For him Germany stands for a nation that must be ostracized into eternity for past transgressions and a currency manipulator in modern times. Believe he has the capacity but certainly does he not have the inclination to consider any other possibilities.
Certainly does Germany have its own problems and I think it deals with it. But please allow me express a divergent view on some of your made points:
* Even today the wealth distribution in Germany is among the most balanced one in the industrialized world. Do you mind pointing us to a different nation that has a more balanced wealth profile?
* A multicultural paradise? Certainly not. But given how many refugees and immigrants Germany accepted (the highest number in all of Europe as percentage of its number citizens in both categories) the number of racial clashes is a lot lower than, for example, in the US, Spain, Italy, and particularly France. Nothing is perfect but I think Germany has learned a great deal from the 1960s how to better promote and support integration. You have 2nd generation Turkish immigrants sitting in German politics, immigrant entrepreneurs (one of the world's most advanced computer game companies was founded by immigrants in Germany -> Crytek), and you see immigrants sitting on corporate boards. Can things further improved? Certainly.
* National WWII trauma? This applied to my parents but especially my 70s generation. Education nowadays handles this part of history highly responsibly and at the same time Germans have learned to again to display national pride and patriotism. I am not sure how this is connected to a discussion about immigration.
* There is one single group that labels anyone a Nazi and anti-semite who takes a differing stance: Jews. The Central Council of Jews in Germany is an organization that can say whatever it wants and it still can end political careers. Sad but true. That is my biggest gripe, that a majority of Germans has not yet made an effort to shut up those people who have only one goal set before themselves: To again entirely control German media and finance. They have made great efforts on the media side and to the fullest (ab)use their media representation in Germany. This is maybe the last bastion and leftover from the WWII guilt that still holds most Germans captive.
That's one part of the German success, the other part is that Germany is the only country in Europe that has been able to successfully transform their labor market to a model that is more in line with international competition. A lot of worker rights have been abolished and many Germans are now working in so called "minijobs", that barely pay enough to support yourself. Some will call that social injustice but that's how you cope with economic reality. The relative equal distribution of wealth we have seen in the 60s and 70s was a historic anomaly, we're getting back to normal.
Volpunter makes it sound like Germany is some multicultural paradise but it's not. Germany is having it's share of problems with the massive immigration of people coming from backward, tribal cultures. The national trauma about WWII has however smothered a sensible discussion about these problems, even more so than in the rest of Western-Europe. Everyone who even dares to touch the subject is labeled a nazi and a fascist.
