And here is the kicker; Those debts are now held by the ECB, which, is not supposed to be a lender of last resort, but now has become one by default. The corporate banks are now safe and have extricated themselves from the risky position they found themselves in 5 years ago.
The ECB doesn't care either way. Schauble secretly welcomes a Grexit, because without external support Greece can't move to a new Drachma. The logistics are just impossible by themselves. Schauble wants the rest of the Eurozone to witness what will happen when you exit the Euro without support (it won't be pretty).
Hi there France btw. You still like you early retirement, large civil service employment, string unions and social state? Well, you're number one on their hit list.
