Ultimately, Germany owes a lot to the Eurozone. It allows them to have a weak currency and boosts their exports. You'd think they'd be interested in making sure it sticks together...
When can that be more dangerous, when IMF has repeatedly claimed that that's the only way in which the Greek economy will not collaps entirely?
A complete Greek collapse while unfortunal would have little real effect on EZ. While telling any of the other south European countries that the Greek negotiation tactic was a viable option would be potential devastating. Spain if they adopted the Greek negotiation tactic could fully destroy the EZ, and they would be to big a country to save.
I'm not talking about the euro zone, I'm talking about Greece. If all you care about is the euro zone, then you sound like an egoist to me. Btw, Spain has never had a debt problem, it has long been one of the least indebted countries in Western Europe, so I have no idea what you're talking about. Their structural problems are completely different, it's all about unemployment and an unfortunate housing bubble just like we saw in the US and now in China. That's more a sign of excessive prosperity than disaster in a way.
