What about "common sense" predicts Greek default? How is that this software do not predicts USA default too? USA is in the same situation that Greece is and those Geniuses continue expending trillions in Irak and Afghanistan.

They could use massive inflation or face default, one way or another they are not going to pay what they indebt.
