Tinker,
Greece accepted no loss. The people who Greece owed money too (bond holders) took a loss.
Mr. Perfect,
I've been busily relocating to Europe recently, and I think your perspective is largely correct. Europe is like the US, but worse and better. Worse in economic reality, better in practice through superior suspension of disbelief and more powerful central authority. (It is also fundamentally poorer in ways most Americans or Europeans don't appreciate.) The EU will likely collapse and the Euro with it (or vice versa.) But it won't be any more an end of the economic world situation than the housing collapse before it was.
Demon of Undoing,
Many powerful organizations and brilliant individuals are implementing plans to correct this problem. Unfortunately, political realities make the problem impossible to solve, and furthermore make it impossible for the political system to accept this impossibility. Europe is still in the denial phase of accepting its own death.
