Get the Summary of Nouriel Roubini''s Megathreats in 20 minutes. Please note: This is a summary & not the original book. Original book introduction: Renowned economist Nouriel Roubini was nicknamed "Dr. Doom," until his prediction of the 2008 housing crisis and Great Recession came true--when it was too late. Now he is back with a much scarier prediction, one that we ignore at our peril. There are no fewer than ten overlapping, interconnected threats that are so serious, he calls them Megathreats. From the worst debt crisis the world has ever seen, to governments pumping out too much money, to borders that are blocked to workers and to many shipments of goods, to the rise of a new superpower competition between China and the U.S., to climate change that strikes directly at our most populated cities, we are facing not one, not two, but ten causes of disaster. There is a slight chance we can avoid them, if we come to our senses—but we must act now.
