Prediction: it will last, debt will be somehow converted to "value", and everyone in US will feel that they are better off now wrt the rest of the planet, making others more and more miserable (wars, their property being taken by US capitalists, etc).

Unless someone stops finally US. And even then I am not sure that it will bring good, because before drowning, they will try to take all the others with them. After all, "it's theirs"..
