It seems to be a tricky situation right now, and I honestly have no idea by myself how to solve it in a way so that investors don't lose their money and the people in greece don't end up in massive poverty.
Currently my own ideas are very extremistic in one way or another:
a) intervene with military force and set up a temporary government that pushes much needed laws, ensures that taxes are paid without exceptions and fights corruption without mercy. This way the society can be transformed and modernized.
b) All EU states give up their antique national mindsets to form the united states of europe, this way all dept is combined into the EU entity and a new central government can deal with it on large scale effectively. I personally would love this, no matter the circumstances.
c) Increase lendings massively without the austerity politics, so the greece folks can actually start to invest and trigger positive economic signals. But I think this delays just the fundamental problems...
So, what do HNers think about this topic? Is there any viable solution for the current situation?
The fact is the EU currency union was deeply flawed from the beginning, and favors exporting economies like Germany over a tourism/shipping economy like Greece. Greece was the fastest growing economy in Europe for decades prior to joining the Euro, and given its immense advantages, there's little reason to suspect this wouldn't have continued in a fair and equitable union, despite corruption & overspending.
Invading Greece to recoup the losses of large banks is not only insane and unethical, but will undoubtedly be met by the bloody resistance of a proud people. It would probably lead to a third world war, which the EU was created to prevent. Your option B is a better union, but it seems very unlikely to happen.
The best bet is what is going to happen anyway .. Greece will leave the Euro, struggle to get back on its feet, but once it does it will prosper as currency devaluation will play to its strengths as the most enticing per capita tourism mecca in the world.
