Quite by design. Having the whole Europe on Germany's monetary policy (i.e. Eurozone with EUR interest rates) while not sharing any other policy is heavily in Germany's favour and one of the main reasons the European debt crisis happened.
Not to say that being a well governed country with good policy and a culture that is conducive to high productivity and good quality did not help - it definitely did. And I'm not trying to redirect blame for the Eurozone crisis - Greece has mainly itself to blame.
