The Euro as a currency has not been well designed. Consequently this has led to countries becoming heavily indebted and unable to pay back the debts. Unlike the U.K, U.S, Canada, Sweden, and others, Greece does not have its own currency. Its debts are denominated in Euros, and only the European Central Bank can create via ECB Bonds. So unlike countries with a Sovereign Currency, whom can print money to pay back their debts, Greece must beg for more Euros from the other Europeans.
I say let Greece fail!! The banks that irresponsibly financed Greek debt must suffer the consequences, this is how the market should work. The E.U should then finance Greece, as she creates her own currency, and the necessary institutions. The European Banks want the ECB to print a heap of Euros, so that they can be paid for the bad loans given to Greece. This exit from the Euro currency will rescue the Greek people from unnecessary suffering, and force the Banks to deal with the mess they have caused.
