"Europe should learn from history. But it needs to learn fast. There might be no recovery unless debts are reduced to manageable proportions. That is what ended the Great Depression in Europe in the 1930s, and that is what in all likelihood is needed again. Professor Sinn is right to resolutely ask for action on this, even if his take on the Marshall Plan is wrong."
