"This is really odd that economists are expected to predict the future, because no on expect other people in other disciplines to predict the future. Nobody says to the biologists: What is the next stage in evolution? If you can't expect the next stage in evolution... well I guess biology just isn't a science and, that no one should listen to you. Nobody says to the political scientist: Well... you know, who is going to win the next election? If you can't tell me now, then I guess, you know, political science does not mean anything. But somehow economics takes this burden, that people in economics are supposed to be able to forecast the future."
