Right now, the Greeks are going through the various stages of mourning: first, they ignored the fact that their economy was collapsing (denial). Now, they are beyond denial and are at the angry stage, hence the riots.
When the chickens come home to roost, everyone is shocked, SHOCKED that such a thing could happen. And Americans are looking at their future on the TV screen right now as the mobs scream for their promised gold, which has been gone for a long time. When it comes time for Geraldo Rivera to open up that vault door, and the TV cameras zoom in, the Greeks will find that instead of the tons and tons of gold their leaders promised them, there is nothing inside that vault that was plundered by their leaders for generations; nothing but dirt.
Reality sucks, sometimes. Especially when you realize that you have been duped your entire life by socialists that Socialism works. We have breaking news for Greece, Italy, Portugal and Spain (and the US): Socialism doesn't work.
Eventually you run out of everyone else's money.
