Every politician worth his salt is “WHISTLING IN THE GRAVEYARD”, trying to to tell every body that a GREEK collapse isn’t going to do anything to the world’s economy. When somewhere in somebody’s back room, they are trying to figure out how to get out of this hole they’ve dug for themselves. It may take a few months, but eventually, even these people will realize that the world economy needs re-adjusting. What they are also probably doing is saving their skin, by preparing to make sure none of them will get hurt too terribly, when the crash comes. The only ones that really get hurt are the poorest people in this world. As for the regular people that own gold or silver, the government will just make it a crime to personally own any of these precious metals.
Sorry, little effect globally. Of course, the Greeks will eventually end up aligning with the Communists to survive but in the end, they are big losers. Vote for Socialism, get your rewards...
