They provided for themselves no better than they had previously been provided for, and would still have been provided for, by the men whom they displaced. The whole somber incident is unrelieved by a single gleam of light. Previously to this invasion of the industrial field by woman there had arisen conditions that were in themselves peculiarly menacing to the social fabric. Some of the philosophers of the period, rummaging amongst the dubious and misunderstood facts of commercial and industrial history, had discovered what they were pleased to term "the law of supply and demand"; and this they expounded with so ingenious a sophistry, and so copious a wealth of illustration and example that what is at best but a faulty and imperfectly applicable principle, limited and cut into by all manner of other considerations, came to be accepted as the sole explanation and basis of material prosperity and an infallible rule for the proper conduct of industrial affairs. In obedience to this "law"--for, interpreting it in its straitest sense they understood it to be mandatory--employers and employees alike regulated by its iron authority all their dealings with one another, throwing off the immemorial relations of mutual dependence and mutual esteem as tending to interfere with beneficent operation. The employer came to believe conscientiously that it was not only profitable and expedient, but under all circumstances his duty, to obtain his labor for as little money as possible, even as he sold its product for as much. Considerations of humanity were not banished from his heart, but most sternly excluded from his business. Many of these misguided men would give large sums to various charities; would found universities, hospitals, libraries; would even stop on their way to relieve beggars in the street; but for their own work-people they had no care. Straman relates in his "Memoirs" that a wealthy manufacturer once said to one of his mill-hands who had asked for an increase of his wages because unable to support his family on the pay that he was getting: "Your family is nothing to me. I cannot afford to mix benevolence with my business." Yet this man, the author adds, had just given a thousand _drusoes_ to a "sea-man's home." He could afford to care for other men's employees, but not for his own. He could not see that the act which he performed as truly, and to the same degree, cut down his margin of profit in his business as the act which he refused to perform would have done, and had not the advantage of securing him better service from a grateful workman.
