The Theory of Productive Forces (sometimes referred to pejoratively by opponents as productive force determinism) is a widely-used concept in communism and Marxism placing primary emphasis on achieving abundance in a nominally socialist economy before real communism, or even real socialism, can have a hope of being achieved.
The concept has been used in all examples of state-supervised socialism to date. Joseph Stalin is one proponent of this view. The most influential philosophical defence of this idea has been promulgated by Gerald Cohen in his book Karl Marx's Theory of History: A Defence. According to this view, technical change can beget social change; in other words, changes in the means (and intensity) of production causes changes in the relations of production, i.e., in people's ideology and culture, their interactions with one another, and their social relationship to the wider world.
In this view, actual socialism or communism, being based on the "redistribution of wealth" to the most oppressed sectors of society, cannot come to pass until that society's wealth is built up enough to satisfy whole populations. Using this theory as a basis for their practical programmes meant that communist theoreticians and leaders, while paying lip service to the primacy of ideological change in individuals to sustain a communist society, actually put productive forces first, and ideological change second.
The Theory of Productive Forces is behind Stalin's Five Year Plans, Mao Zedong's Great Leap Forward, and most other examples of attempts to build and refine communism throughout the world in the 20th Century, although Maoism's subsequent concept of the need for a Cultural Revolution did signal some limited steps away from reliance on the theory. The philosophical perspective behind the modernizing zeal of, in particular, the Russian and Chinese communists seeking to industrialize their countries is perhaps captured best by this thought in The German Ideology by Marx and Engels.
Seems pretty innocent on paper. Except Stalin caused the death of about 20 million people and Mao the death of about 40 million, together more than all the people who died in WWII (55 million).
