What a lot of people don't understand is that all the debt in the system acts like a major pressure to create demand for US dollars. Once they pop the bubble, and you have massive bankruptcies, all that pressure will go away, and the US dollar will become shit. It hasn't happened before, because the US could always go into more debt and people could credibly believe that we could pay it back, but they are going to be in for a rude surprise this time.
