The conclusion to which we are forced by theoretical considerations is fully endorsed by observation of actual life. It is sufficient to indicate broad facts to one who denies moral progress. Slavery, which Aristotle thought a law of Nature, which Christianity tolerated, which modern states, such as England, France, the United States and Brazil, defended and protected by law, was everywhere abolished some years ago. The objection is raised that modern hired labour is merely slavery of the proletariat under another name, that the exploitation of workmen by employers is a hypocritical continuation of serfdom. But that is sophistry. The hired labourer is not bound to his contract. He can break it. "Yes, at the price of starvation." That used to be the case, but nowadays organized working men are no longer at the mercy of powerful capital, and therein lies progress. They are in a position to make conditions and not seldom to force their acceptance. They have the right to strike, to move from place to place, to form unions. The community has recognized the duty of mitigating, at least to some extent, the evils to which faulty economic organization exposes the workman. It has instituted accident and health insurance, old age pensions, and, in some places, assistance for those who are out of work through no fault of their own. All this is still very defective, but these are hopeful beginnings, all the same, and, above all, it shows the awakening of a social conscience that earlier ages did not know.
