Marc Faber : The breaking point could be three, four, five years away. The world is heading toward a major crisis. In the meantime, central banks can continue to print money and markets might move up. Since 2009 stocks around the world have more or less doubled. But the economy hasn't performed well, and the typical household hasn't been helped. With quantitative easing, money flows into the hands of relatively few people. I am very negative about the outlook longer term.
It is safest to buy U.S. Treasuries because the U.S. can print money. It will pay the interest. But you are earning only 1.6%, and the cost of living is increasing by about 5% a year around the world. You are getting a negative real return. - in Barron's roundtable June 2012
