The system as it now stands divides the world into two spheres--a small one, in which a few live surfeitingly by owning, and a large one, in which the many live starvingly by working; and, yet, ultimately, absolutely everything for both depends upon the worker and nothing at all on the owner. Yes, the worker is indispensable to the owner, as much so as (to use the classical illustration) the dog to the flea; but the owner is no more indispensable to the worker than a flea to a dog. As dogs would be much better off without fleas, so would workers without owners. The discovery that the itch is caused by a parasite was of an epoch making character because it led to the discovery that many, if not most of the diseases by which mankind and also animal kind are afflicted are of a parasitical character. This is as true of the social organism as of the physical. Capitalism is the tape worm of society. The existence of the master and slave classes inevitably gives rise to four struggles: (1) the struggle of the slaves with the master for better conditions, issuing in rebellions; (2) the struggle between masters for advantages in markets, issuing in wars; (3) the struggle between the slaves for jobs, issuing in a body and soul destroying poverty; and (4) the struggle of the slaves with the master for a reversal of conditions, issuing in revolutions. All this struggling between the classes and within them tends towards two results with both classes. In the case of the master class, these results are the making of the rich fewer and the remaining few richer. In the case of the slave class, these results are the making of the miserable poor more numerous and all less happy. While capitalism stands, all talk about peace on earth and good will among men will be so much hypocrisy; for, until it falls, the world will be divided into the slave and master classes and these four contentions with these results will continue to fill it with hatred and strife. II. The overthrow of capitalism in Russia is the greatest event in the history of the world and it has converted International Socialism (the Marxian revolutionary kind) from a theory into a condition. Theories come and go. Conditions remain and work. From this on revolutionary socialism will be working, night and day, with might and main, here and there, everywhen and everywhere, and its three herculean tasks are: (1) to dethrone the great imperialist, competitive capitalism; (2) to enthrone the great democrat, co-operative industrialism; and (3) to make the world safe for an industrial classless democracy.
