This, however, is somewhat apart from our argument. The main point, of which we must not lose sight, is that the private ownership of those gifts of Nature which are widely distributed operates to the general benefit of the community far more than any system of public ownership that could be devised. But, on the other hand, in the case of natural agents limited in amount, it is practically certain that sooner or later a monopoly will be established by their private owners, to the serious detriment of the public at large. The sovereign right of the public in this latter case to take such steps as are necessary for its proper protection, is something which both _a priori_ reasoning and judicial decisions amply prove. The great problem of monopoly would be a far easier one to solve, both theoretically and practically, were it as easy to regulate justly those forms of monopoly whose strength lies in combination only, as it is those whose power depends on the possession of gifts of Nature, which we have just considered. In dealing with trusts, monopolies in trade, and labor monopolies, we are in danger, on the one hand, of sanctioning oppressive interference with private business, and on the other of permitting a license in the conduct of private business which encourages its managers to continue to extort unjust gains from the public. In the face of this difficulty, which careful consideration shows to be very serious, and in the dread of other evils, such as the government proving incompetent to safely undertake these new and strange responsibilities, we may well feel like trying to get along with the aid of those old defenses against monopolies that have always, until the modern concentration of industry was accomplished, been ample to hold them in check. But the one argument which prevents this is the fact that this tendency to concentration and consolidation is still actively at work. In the words of Prof. Ely: "Production on the largest possible scale will be the only practical mode of production in the near future." It is for this reason that we must not cease to look about for some better protection against this new class of monopolies than are afforded by merely placing stumbling-blocks in their way. We shall have need, for many years yet, of such weapons in fighting monopoly as the public is already familiar with; the creation of new competitors and their support by public opinion, judicial decisions against combinations, and the like. But before these grow absolutely useless, we ought to be prepared to meet the new conditions of industry with something better than mere opposition; and even now be experimenting and studying upon a permanent and consistent policy.
