Yes. There's plenty of ways out of this impasse, but they're all catastrophic.
The Germans are finally talking seriously about much closer political integration as being the only non-catastrophic solution, but it is not actually a viable solution at all because the eurozone nations are all democracies and the treaty for full political union will have to be agreed by the electorates of those countries. The only way such a union could actually come about (at all probably, but certainly in the timescale required) is by over-riding the democratic rights of the people of Europe - it would have to be implemented whether the people vote for it or not. Any question marks about whether it could be shot down by, say, a no vote in Ireland, would make it useless in the eyes of the markets. So it isn't going to happen, because the electorates of Europe are becoming more and more anti-European, not pro-European. Sure, they want to keep the euro, but they do not want to be ruled from Brussels and Berlin, and they will not accept this being imposed against their democratic will, especially if it involves vicious austerity programs which won't even work!
The euro-experiment is over. It was badly put together in the first place, and it has failed at the first serious test of its integrity. Nobody in Europe is ready to admit this yet, but the fact that both the Bank of England and the Federal Reserve are now saying they are "ready to act" indicates just how serious the situation is. This can only mean they are ready to print pounds and dollars to keep the European banking system from total collapse, and it is the first real hint that we are heading towards death-by-inflation rather than a UK/US sovereign default. The c**ts who are still running the world will just keep printing money as the whole world descends into political and economic chaos.
