The development of the economy in the West after the war also exerted a great influence on the spread of opportunist and revisionist ideas in the communist parties. True, Western Europe was devastated by the war but its recovery was carried out relatively quickly. The American capital which poured into Europe through the “Marshall Plan” made it possible to reconstruct the factories, plants, transport and agriculture so that their production extended rapidly. This development opened up many jobs and for a long period, not only absorbed all the free labour force but even created a certain shortage of labour.
This situation, which brought the bourgeoisie great superprofits, allowed it to loosen its pursestrings a little and soften the labour conflicts to some degree. In the social field, in such matters as social insurance, health, education, labour legislation etc., it took some measures for which the working class had fought hard. The obvious improvement of the standard of living of the working people in comparison with that of the time of the war and even before the war, the rapid growth of production, which came as a result of the reconstruction of industry and agriculture and the beginning of the technical and scientific revolution, and the full employment of the work force, opened the way to the flowering amongst the unformed opportunist element of views about the development of capitalism without class conflicts, about its ability to avoid crises, the elimination of the phenomenon of unemployment etc. That major teaching of Marxism-Leninism, that the periods of peaceful development of capitalism becomes a source for the spread of opportunism, was confirmed once again. The new stratum of the worker aristocracy, which increased considerably during this period, began to exert an ever more negative influence in the ranks of the parties and their leaderships by introducing reformist and opportunist views and ideas.
Under pressure of these circumstances, the programs of these communist parties were reduced more and more to democratic and reformist minimum programs, while the idea of the revolution and socialism became ever more remote. The major strategy of the revolutionary transformation of society gave way to the minor strategy about current problems of the day which was absolutized and became the general political and ideological line.
