There is no such thing.
Germany pays interest on most those loans itself, and if Germany would just hand out money to Greece as it is, the market would judge that negatively, and thus interests go up.
Its nearly the best thing. Whats debated is the German & Co public loans also needing to be written off, but where would you be then without the "evil banks" slurs?
I get its frustrating but would it be any less in whatever given scenario?
