> Greece has no real alternative but to adopt severe reforms and that means severe "austerity", whereby "austerity" of course what people mean is shrinking the Greek state to a size more appropriate to the size of its economy. Greece has a perfectly workable alternative in a Grexit. It would help them enormously and not require austerity but there are political reasons that won't allow it. If Greece was using the dra…
As a purely economic solution, a Grexit combined with a default might work. However, who would step up and finance the ongoing deficit? Interest rates even for short term borrowing would be unsustainable. What would happen in the meantime, until such a Grexit could actually be performed? The banks don't have money any more, there's no infrastructure to print new bills, there's no plan on how to actually do that. It's…
As I added in my edit, Greece has a primary budget surplus. There would be no ongoing deficit.
Existing debt would be paid off with the expedient of default and currency devaluation, just as other countries have historically done. A little rough patch and then things look up. Seems a much healthier alternative than decades of economic suffering due to more and more austerity and the consequences thereof.
> there's no infrastructure to print new bills
I can't imagine that is a very hard problem to solve.
> On top of that, would Greece leave the EU? There's a lot of greek living and working abroad under the EU residence/work rules. Would such a vote not be perceived as a "No" to europe, effectively pushing greece out of the EU at least on a temporary basis?
Does leaving the Euro mean leaving the Eurozone? That's an honest question. I don't think it does, but I've heard this said before.
On your final point, I don't disagree: at least right now leaving the Eurozone is politically untenable. But I suspect that economically it might be the most sensible thing to do, and not just for Greece. Unless Europe forms a real fiscal union, this kind of madness will happen over and over.
