US super-investor Warren Buffett is predicting a collapse of the American economy. He made this forecast in his annual message to the shareholders of Berkshire Hathaway Inc. In Buffett’s opinion, there is no reason to talk about the end of the recession and the lack of danger of a new crisis. The number of unemployed does not give reasons for optimism either. Even though it has dropped a little, it is still far from pre-crisis figures, said Viktor Supian, the deputy director of the Institute of the USA and Canada at the Russian Academy of Sciences in his interview for “The Voice of Russia”.
