@hawkeye10,
The damage to the Greek economy has been accumulating for several decades under corrupt governments that accumulated unsustainable debt loads to finance the social welfare probrams they used to keep themselves in power, and a highly reculated economy that they used to enrich themselves and their supporters through crony deals and bribery.
The added damage that occurred over the past months is substsantial, but small compared to the problem that has been growing for the past four decades (at least). It was the price of the denial of the Greek populace and ruling parties about the reality of their situation. It has proven hard to persuade northern European countries to subsidize public pensions in Greece that are more generous than their own. That's not likely to change. One can hope that now the Greek people will focus on their own economic productivity as the only reliable solution to their chronic problems.
I don't know what else Germany could have done in these circumstances. The Spanish, Italian and French economies have their own problems as well, and there was real danger the contagion could spread. I believe French President Hollande was only too happy to stand in Merkel's shadow making sympathetic but empty gestures toward the Greeks while knowing that the rest of Europe doesn't have the ability to subsidize the Greeks any longer, while Germany certainly doesn't have the ability to bail them all out if present trends continue. The piper had to be paid, and the price the next time will be much higher. Perhaps now the Spanish recovery will continue and even the Italians and French might get the message.
