Marx established labor justice on the basis of criticizing capital justice, hence reformed the justice theory. Marx’s critique of labor justice focuses on labor alienation, which reduces labor from a free and conscious internal activity to a tool and means for capital proliferation, and workers lose their dignity. Criticizing labor alienation is to achieve labor liberation, and the fundamental way to eliminate labor alienation is the communist movement. The liberation of labor through the communist movement is to achieve the free and comprehensive development of human beings, who thus become the “Total Man.” Marx’s labor justice view reveals that we must keep the dominant position of the public ownership of the means of production, adhere to the value of becoming wealthy through hard work, promote labor education in universities, and primary and secondary schools, and adhere to green development.
