Hmmm...you mean life isn't fair? Have you told anyone else about this?
A country is a big insurance policy...when it operates within its means. When it doesn't, then it is a large unhappy family because SOME family members were thinking only of themselves and not the rest.
Morals, or more accurately, ethics, are inescapably tied to economics. One has to accommodate and pay restitution for sins of the past. The sins of the future must be prevented by ethically thinking ahead for the future of the country. Greece wants to ignore the sins of the past and ask forgiveness without taking responsibility. They also want to sow the sins of the future by claiming the ethics necessary to avoid them are beyond anything they can do.
That said, the Euro politicians aided and abetted the behavior of Greece. And for that, the rest of Europe will pay one way or another. It matters who you elect to office. The U.S. has similar problems with politicians who refuse to pay for the past deficits in spending and won't acknowledge future debts, all on some misguided belief that that OTHER party is mainly at fault.
