You can't have a workable monetary union without a fiscal union. Germany wouldn't have such a big surplus if its exports weren't massively boosted by the southern states depressing the exchange rate of the Euro. Unions require unity, and if Germany feels like its pulling more than its own weight, it can exit. But you see exactly the opposite, Germany (at least nominally) states that its goal is to preserve the union, and this betrays the fact that the union brings massive advantages for the German economy. It is not out of a sense of benevolence and european solidarity, but of pure self-interest.

Well, if Germany and the North want the union to survive, they will have to treat it like a real partnership and respect and recognize the contribution of their other partners.

The current "solution" of bailing out Italy and Spain with even more debt on the condition of further future austerity will only lead to further instability, unemployment, discontent and financial ruin when the debts come due.

It is not a question of "solidarity" with the South. It is a question of whether the North recognizes the contribution of its partners to the union, and whether they can act in mutual self-interest to save it.
