Under the conditions of mass production, in order to meet the needs of society for various use-values, it is necessary to pay various types of labor, and it is necessary to allocate the total social labor according to the corresponding proportion of various use-value needs. This passage mainly supports the view that:. ['In social production, the demand for various use-values is different.', 'The distribution of total social labor should be adjusted through the law of market value.', 'The use-value of labor is realized in the distribution of total social labor.', 'Proportionate distribution of total social labor is not shifted by human will.']
