I don’t see a revolution either but I do see a situation so bad that there is a wide spread call to change the system to a more equitable one. (Flat tax, term limits on congress people, balanced budget mandatory, replacing the dollar with another currency, …)The book “aftershock” by weinamer (or something close to that) spells it all out. I am a little surprised that greenspan is saying something similar to what aftershock says. ( If you read between greenspan’s words). This is the first time I have heard a mainstream economist reference a catastrophe if the debt load isn’t reduced. In short, aftershock says that we are in for a dollar bubble which leads to a Treasury bond bubble/default.
