The Greeks have devolved into arrogant beggars. They are similar to raging adolescents who are demanding a doubling of their allowance and refuse to do any real work. Such people usually end up as delinquents.
The only way out for Greece is to default and go back to the Drachma. It will be very painful for awhile, but staying with the Euro they will be crushed for decades trying to pay back those debts.
