And here we are not wholly left to our imaginations, not wholly without experience to guide us. In actual practice to-day, in those industries in which the organization of the workers into unions has been most successful, the workers, through their organizations, do exercise a certain amount of control over the conditions of their employment. Their right to share in the determination of the conditions of labor is conceded. They make trade agreements, for instance, in which such matters as wages, hours of labor, apprenticeship, output, engagement and discharge of workers, and numerous other matters, are provided for and made subject to the joint control of the workers and their employers. Of course, this share in the control of the industry in which they are employed is a right enjoyed only as a fruit of conquest, won by war and maintained by ceaseless vigilance and armed strength. It is not inconceivable that in the Socialist state there might be a frank extension of this principle. The workers in the main groups of industries might form autonomous organizations for the administration of their special interests, subject only to certain fundamental laws of the state. Thus the trade unions of to-day would evolve into administrative politico-economic organizations, after the manner of the mediaeval guilds, and become constructive agencies in society instead of mere agencies of class warfare as at present. The economic organization of the Socialist state would consist, then, of three distinct divisions, as follows: (1) Private production and exchange, subject only to such general supervision and control by the state as the interests of society demand, such as protection against monopolization, sanitary laws, and the like; (2) voluntary cooeperation, subject to similar supervision and control; (3) production and distribution by the state, the administration to be by the autonomous organizations of the workers in industrial groups, subject to the fundamental laws and government of society as a whole.[190] VI
