Furthermore, the nature of certain of the forces which account for the low wage levels of the groups that would be affected by the living wage policy, give the above argument special force. For among those forces are these: that their wages have been, at times, less than the amount necessary to enable them to do as efficient work as they were capable of doing; and so low, frequently, as to make the struggle for self-improvement and advancement, for members of these groups, a very difficult matter. Thus the numbers in these groups have been kept greater than they would have been otherwise. Furthermore, their wages have been, at times so low that efficient industrial management counted little in success. Furthermore, these groups have had practically no organization or leadership to prevent their employment under conditions most unfavorable to their health, energy, and general welfare. And lastly, that the present industrial system has a tendency to take advantage of economic weakness wherever it exists. Against these considerations must be put, perhaps, the submission shown by these groups to the course of industrial development, and the constant service they have given, in their position of dependence, in monotonous and wearisome work. The case of the living wage policy rests upon the opinion that the introduction of living wage standards will give rise to a series of adjustments in production and distribution. And that the net sum of the results of these adjustments, perhaps only after a temporary period of dislocation in some instances, will be to increase the wages of the lowest grades of wage earners--without doing equivalent harm in any other direction. It also rests on the opinion that the permanent economic advancement of these lowest groups of wage earners is a practicable ideal--though fate seems to take a special delight in dealing harshly with this particular ideal.
