The point is that complacency almost always ends suddenly. You just don't slide gradually into a crisis, over years. It happens! All of a sudden there is a trigger event, and it is August of 2008. And the evidence in the book is that things go along fine until there is that crisis of confidence. There is no way to know when it will happen. There is no magic debt level, no magic drop in currencies, no percentage level of fiscal deficits, no single point where we can say "This is it." It is different in different crises.
