The variation of economic society from its static standard offers a problem for solution, and in this connection the type of change in which the most serious evils inhere is that which discards old technical methods and ushers in new ones. The question whether these evils are destined to increase or to diminish we have answered conditionally on the basis of past experience and present tendencies. If competition continues and labor retains its mobility, the evils will naturally grow less. The grand resultant of all the forces of progress is an upward movement in the standard of economic life gained, not without cost, but at a diminishing cost.

A vital question is that of the continuance of the movements now in progress. Do any of them tend to bring themselves to a halt? Is any change on which we rely for the hopeful outlook we have taken self-terminating? We have found that the growth of population tends to go on more slowly as the world becomes crowded, while the motives for an increase of productive wealth grow stronger rather than weaker. Technical progress gives no hint of coming to an end, and improvements in organization may go on indefinitely, though they will naturally go on more slowly as the modes of marshaling the agents of production are brought nearer to perfection. Knowledge of the causes of economic change is at best incomplete, and enlarging it by the statistical method of study will be a chief work for the economists of the future. Analytical study points distinctly to a coming time of increased comfort for working humanity. Progress gives no sign of being self-terminating, so long as the force which has been the mainspring of it, namely, competition, shall continue to act.

The suspicious element in the general dynamic movement is progress in organization. That which we have primarily studied is the marshaling of forces for mere production—the creation of efficient mills, shops, railroads, etc. This, however, carries with it a tendency to create large mills, shops, and railroad systems, and, in the end, to combine those which begin as rivals in a consolidation in which their rivalry with each other ceases. This means a danger of monopoly, and is the gravest menace which hangs over the future of economic society.

If anything should definitely end competition, it would check invention, pervert distribution, and lead to evils from which only state socialism would offer a way of escape. Monopoly is not a mere bit of friction which interferes with the perfect working of economic laws. It is a definite perversion of the laws themselves. It is one thing to obstruct a force and another to supplant it and introduce a different one; and that is what monopoly would do. We have inquired whether it is necessary to let monopoly have its way, and have been able to answer the question with a decided No. It grows up in consequence of certain practices which an efficient government can stop. Favoritism in the charges for carrying goods is one of these practices. Railroads have become both monopolies and builders of other monopolies. Certain principles, which we have briefly outlined, govern their policy, and the natural outcome of their working is consolidation. This creates the necessity for a type of public action which is new in America—the regulation of freight charges.

Akin to this is the necessity for keeping alive competition in the field of general industry by an effective prohibition of various measures by which the great corporations are able to destroy it. The dynamic element in economic life depends on competition, which at important points is vanishing, but can, by the power of the state, be restored and preserved, in a new form, indeed, but in all needed vigor. With that accomplished we can enjoy the full productive effect of consolidation without sacrificing the progress which the older type of industry insured.

The organization of labor, its motives, its measures, and its tendencies,—including a tendency toward monopoly,—we have examined. Through all the wastes and disturbances which the struggle over wages occasions we have discovered a certain action of natural economic law, and have seen what type of measures, on the part of the state, will remove impediments in the way of that law and enable it to act in greater perfection.

Connected with the dynamic movement on which the future of society depends are the policies of the government in connection with currency and with protective duties. Here, less action, rather than more, is demanded on the part of the state. While no renewal of a laissez-faire policy is possible, a reduction of the duties which now play into the hands of monopoly is distinctly called for. In connection with currency a greater trust in nature and a smaller reliance on governments will give the best results.

Our studies have included, not the activities of the whole world, but those of that central part of it which is highly sensitive to economic influences. The whole producing mechanism here responds comparatively quickly to any force which makes for change. This society par excellence is extending its boundaries and annexing successive belts of outlying territory; and as this shall go on, it must bring the world as a whole more and more nearly into the shape of a single economic organism. The relations of the central society to the unannexed zones are attaining transcendent importance, and a fuller treatment of Economic Dynamics than is possible within the limits of the present work would give much space to such subjects as the transformation of Asia and the resulting changes in the economic life of Europe and America. Here again the conscious action of the people determines the economic outcome. In the main we can still leave the natural forces of industry to work automatically; but we have passed the point where we can safely leave to self-regulation the charges of the common carrier, the conduct of monopolistic corporations, or certain parts of the policy of organized labor. Foreign relations are, of course, a subject for public control, and they are coming to affect in a most intimate way our own economic life. Everywhere our future is put into our own hands and will develop the better the more we know of economic laws and the more energy we show in applying them. The surrendering of industries generally to the state may be avoided, and the essential features of the system of business which evolution has created may be preserved; but to keep this system free from unendurable evils will require, on the part of the people, a rare combination of intelligence and determination. It will require a public policy that shall neither be hampered by prejudice nor incited by ebullitions of popular feeling, but shall be guided through a course of difficult action by a knowledge of economic law.
