I am a big fan of Kyle Bass. He is one of the few guys that seems to be able to take a 30,000 foot view of the world’s economy. He then breaks it down into very common sense and 8th grade math. His viewpoint is we are mathematically screwd.
Bass lays out the case that Japan will be next on deck after Europe blows (and it will). Rather than get into the stats, just watch the two videos. It is well worth your time.
