The economic policy of Roosevelt's New Deal stays in sharp contrast to the course followed by European policy since 2009. At first, Roosevelt focussed on fighting the desperate feelings of people and the generally pessimistic mood of the public, on strictly regulating the financial sector and on setting up investment and employment programs. After that, structural reforms were carried out in order to strengthen confidence and social coherence. The most important measures were the introduction of unemployment insurance and of a public pension scheme as well as regulations to ensure "fair" labour conditions. The New Deal policy was successful: GDP expanded in the USA between 1933 and 1937 by 43 percent, mainly due to a boom in investments (+140 percent). By fighting the social-psychological depression and "speculation with other people's money", Roosevelt anticipated those two main messages of Keynes' "General Theory" (1936) which were later forgotten: first, the importance of uncertainty and the "state of confidence" and, second, the necessity to radically restrict financial speculation.
