Human history revealed by historical materialism is not only a succession process in which human being is passive, but also a changing process in which human being is active. It is not a simple determinism that human freedom and liberation is completely controlled by the material conditions of production or the natural evolution of the technology itself. Human’s labor force is the most important in the change of history. The labor process of material production is not only the production of wealth, but also a realization process of the human creativity, the potential and dignity. Therefore, in the generation perspective of historical materialism, only the production modes promoting people’s practical ability are moral and desirable, and the morality formed by the laborer in the labor process should have the priority. The moral claims of historical materialism still have moral charisma in contemporary.
