I kind of agree with you Irlandos, the reason being I don't see an out from the current conditions that Greece is experiencing. So given the choice of 20+ years of this compared to going back to our own currency, I'd prefer our own currency.
But to do this the greek people need to understand the full consequences of such a drastic move and I don't know if they're prepared for it. They seem to want to stay in the Euro but not have austerity. Currently, that position is illogical.
The bigger problem is the political cost. The remaining EU countries will be very pissed that Greece found an "out" and will want pay-back in some form. We would have no support from them in the future with issues regarding Skopje or Turkey.
The only viable option is Greece leaving the EU with the EU's "permission" but this is still a long way off. Maybe that is what Greece really wants ? It might explain why they keep dragging their feet.
