Billionaire hedge fund manager Seth Klarman is dominating headlines at the World Economic Forum after writing in a letter that the global economy can not continue "business as usual." Klarman oversees the $27-billion hedge fund Baupost Group and said in a letter seen by New York Times' Andrew Ross Sorkin that the growing political and social divide worldwide could usher in an economic disaster. The world simply cannot continue "business as usual" amid worldwide protests, riots, government shutdowns and other trends that are resulting in a "world increasingly adrift," the letter reportedly said.
