The Germans went through a lot of drama reining in their social spending back in about 1996/97, while it was wildly unpopular it did not end up meaning they'd never elect a Conservative (By European standards) government ever again, because on the whole the Germans tend to be a pretty pragmatic bunch in the long run.
I am not sure at all that Greece and Italy are going to turn out that way. All the financial wizards are looking at Papandreou resigning (And now Berlusconi) as positive steps toward new austerity governments in their respective countries, but I am much more pessimistic about where this will go once new elections and new coalition governments are in full play.
While the Germans take things like tax laws extremely seriously and therefore entitlement program changes and austerity measures have predictable economic outcomes, the exact opposite is true in Italy and Greece, both of which have a completely lackadaisical attitude to income reporting and even payment of taxes at all, but with an unquenchable thirst for personal benefits from the government tit.
