> mechanism to transfer wealth from the northern countries to the southern countries and to make exports easier for Germany
I agree that it works very well for Germany. This, by the way, also implies that the transfer of wealth is not a problem. It is economically reasonable for Germany to pay and the Greek people, for instance, have clearly stated that they want to stay in the Eurozone. Additionally, the Euro can be fixed, it is just currently not politically possible to take the required actions, because the current state of affairs is "good enough". This will change if the Euro is seriously threatened.
