To recapitulate, our economic movement tends toward labor in common, since the operation of the means of production is passing from the working-proprietor to a collective group of laborers, and toward the elimination of the mode or form of private or individual ownership of the means of production, since the nominal property in them is passing from the individual proprietor to a collective body of shareholders (stock-company or trust). It also tends to leave the proprietary class no useful role or function, thus making them for the future not only superfluous, but baneful. At the same time that the organization of labor adapted to the present form and state of the productive forces is escaping from the hands of the proprietary class and is thus the signal that the close of its historic career is at hand, it is concentrating and organizing men everywhere in the same way that it concentrates material wealth. It brings the laborers together and leads them, through their identity in position and interests, to combine in groups or unions, it constitutes them into a class more and more conscious of its situation, disciplines their masses systematically arranged and graded in each industrial establishment, and fashions out of their own ranks an intellectual aristocracy upon which devolves the function of super-intending and managing all industries. And while the individual form of their petty tools or instruments of labor, and their mode of production which keeps them in independent isolation, engender in the workers in petty industries ideas too individualistic and egoistic, wherever modern mechanical industry has already wrested from the laborer his tool and transformed it into a mechanical apparatus effacing individuality from the labor-process, wherever individual labor merges into and blends with collective labor, wherever the technical processes are such that the task of each is of service only through the participation (co-operation) of all, and is itself the condition of the performance of the collective task, the strictly individualistic tendencies of the producers in the petty industries are replaced by the spirit of solidarity, which, with the progress of industrial development, is leading--nay, forcing the working class every day more and more toward socialist ideas, ideas which spring from the material necessities which inexorably force their way into the minds of men.
