There is no way this stops with Greece. The PIIGS, Portugal, Italy, Ireland, Greece and Spain, are about to become bacon.
As long as people allow themselves to accept pretty printed pieces of paper that cost the bankers pennies as actual money, only to return the full face value of that paper as labor plus interest back to the bankers then the people of the world will always live as slaves to the purveyors of pretty printed pieces of paper. The trap of the Reserve system of banking, in which all public currency is the result of a loan from a private central bank is that the moment that first pretty printed piece of paper goes into circulation, more money is owed to the bank than is actually in existence. Debt enslavement is built into the system.
From the bankers' point of view the solution to the debt is to squeeze the peasants harder; to flog them into accepting that they must make do with less so that the bankers may have more.
But from the point of view of the people, who have nothing left to be squeezed out, the more obvious solution is to start hanging the crooks who created the system in the first place, along with the government that sold out the people to the Federal Reserve's machinations almost 100 years ago.
