_Influences which resist Dynamic Movements._--If there is anything which, without impairing the motive powers of economic progress, puts an obstacle in the way of the movement, it has to be treated like one of these elements of friction to which we have just referred. In our discussion of the growth of population, the increase of wealth, the improvement of method, etc., we have paid attention to resisting forces as well as others, and have tried to determine what is the resultant of all of them. The forces of resistance have their place in a statement of dynamic laws. _An Influence that perverts the Forces of Progress._--We have to deal, not only with such retarding influences, but with a positive perversion of the force that makes for progress. Everywhere we have perceived that competition--the healthful rivalry in serving the public--is essential in order that the best methods and the most effective organization should be selected for survival, and that industry should show a perpetual increase in productive power. In our study of the question whether improved method and improved organization tend to promote or to check further improvement, we have found that these beneficent changes are naturally self-perpetuating, so long as the universal spring of progress, competition, continues. A proviso has perforce been inserted into our optimistic forecast as to the economic future of the world--if nothing suppresses competition, progress will continue forever. _Monopoly and Economic Progress._--The very antithesis of competition is monopoly, and it is this which, according to the common view, has already seated itself in the places of greatest economic power. "Competition is excellent, but dead," said a socialist in a recent discussion; and the statement expresses what many believe. There is in many quarters an impression that monopoly will dominate the economic life of the twentieth century as competition has dominated that of the nineteenth. If the impression is true, farewell to the progress which in the past century has been so rapid and inspiring. The dazzling visions of the future which technical gains have excited must be changed to an anticipation as dismal as anything ever suggested by the Political Economy of the classical days--that of a power of repression checking the upward movement of humanity and in the end forcing it downward. No description could exaggerate the evil which is in store for a society given hopelessly over to a regime of private monopoly. Under this comprehensive name we shall group the most important of the agencies which not merely resist, but positively vitiate, the action of natural economic law. Monopoly checks progress in production and infuses into distribution an element of robbery. It perverts the forces which tend to secure to individuals all that they produce. It makes prices and wages abnormal and distorts the form of the industrial mechanism. In the study of this perverting influence we
