The shortening of the general hours of work, then, should be among the primary aims of social reform. There need be no fear that with shortened hours of labor the sum total of production would fall short of human needs. This, as has been shown from beginning to end of this essay, is out of the question. Human _desires_ would eat up the result of ten times the work we now accomplish. Human _needs_ would be satisfied with a fraction of it. But the real difficulty in the shortening of hours lies elsewhere. Here, as in the parallel case of the minimum wage, the danger is that the attempt to alter things too rapidly may dislocate the industrial machine. We ought to attempt such a shortening as will strain the machine to a breaking point, but never break it. This can be done, as with the minimum wage, partly by positive legislation and partly collective action. Not much can be done at once. But the process can be continuous. The short hours achieved with acclamation to-day will later be denounced as the long hours of to-morrow. The essential point to grasp, however, is that society at large has nothing to lose by the process. The shortened hours become a part of the framework of production. It adapts itself to it. Hitherto we have been caught in the running of our own machine: it is time that we altered the gearing of it. The two cases selected,--the minimum wage and the legislative shortening of hours,--have been chosen merely as illustrations and are not exhaustive of the things that can be done in the field of possible and practical reform. It is plain enough that in many other directions the same principles may be applied. The rectification of the ownership of land so as to eliminate the haphazard gains of the speculator and the unearned increment of wealth created by the efforts of others, is an obvious case in point. The "single taxer" sees in this a cure-all for the ills of society. But his vision is distorted. The private ownership of land is one of the greatest incentives to human effort that the world has ever known. It would be folly to abolish it, even if we could. But here as elsewhere we can seek to re-define and regulate the conditions of ownership so as to bring them more into keeping with a common sense view of social justice. But the inordinate and fortuitous gains from land are really only one example from a general class. The war discovered the "profiteer." The law-makers of the world are busy now with smoking him out from his lair. But he was there all the time. Inordinate and fortuitous gain, resting on such things as monopoly, or trickery, or the mere hazards of abundance and scarcity, complying with the letter of the law but violating its spirit, are fit objects for appropriate taxation. The ways and means are difficult, but the social principle involved is clear.
