…co-operative factories… have shown that… to bear fruit, the means of labor need not be monopolized as a means of dominion over, and of extortion against, the laboring man himself

…co-operative labor, if kept within the narrow circle of the casual efforts of private workmen, will never be able to arrest the growth in geometrical progression of monopoly, to free the masses, nor even to perceptibly lighten the burden of their miseries.

Karl Marx, Inaugural Address of the International Working Men’s Association, 1864
