The euro was built around the Bundesbank and therefore every monetary policy taken was more advantageous to Germany then to any other member state. Germany’s strength are exports and if it wasen’t for the rest of the euro area member’s imports, Germany would not be sitting in the high ground and patronising everyone. If all the countries would be exporters, I wonder who would import.
If Germany wants to keep its viability then it needs to help the other members.
There is a much deeper problem in the euro zone then simply lazy people as everyone likes to think. If it were so simple then only Greece would be in trouble.
