Again, the present economic system, built for the profit of the builder rather than for the welfare of the community, represents, not the science of organization for production and use, but the science of organization for exploitation and profiteering. These are some of the reasons why the economic life of the modern world has grown at haphazard. Each industrial director put his own ideas into his business, and as it grew in response to them, the various businesses differed as much in shape, size and character as did the early factory buildings. The time seems to have arrived when a new working plan of economic life may be adopted. The faults and failures of the old are glaring and the clamor for the new is reasonable and insistent. The construction of factory buildings has been evolved into a science. Why cannot the same thing be done with the whole scheme of economic organization? Men no longer erect factory buildings according to personal whim or to the chance ideas of some budding architect. Instead they consult scientists in factory construction who have devoted years to the study and to the practical supervision of the detail of factory building. Can less be demanded of the community which hopes to build its economic life soundly and solidly? A modern steel plant, like that at Gary, Indiana, is carefully planned before a sod is turned. The organization of the works is thought out, sketched, drawn in detail, blue-printed, so that each group of workers that participates in the construction is given a blue print that specifies what is to be done, and where and how. When all of the tasks are completed a steel plant has been called into being. But suppose that each of the eighty gangs of workers, busy on the plant, had followed the lines of its fancy or of its own special interest! The result would resemble the helter-skelter of modern economic society. 7. _Effective Economic Units_ Economic life has been haphazard in the past. In the future it will be one of the most scientifically built of all human institutions. It is so vital a part of the social life, and it yields itself so readily to structural co-ordination that the best structural minds will turn to it perforce, as the logical field for their activities. The economic structure of the future, to be sound, must be built of effective working units. It is as impossible to build a live social system with dead component elements as it is to build a live body with dead cells. At least for the time being, an intricate and complicated structure is needed to handle the problem of livelihood. As time goes on, the nature of the economic system may be greatly modified, and its structure simplified correspondingly. While the complicated economic structure remains, however, the problem will be one of co-relating the activities of vast numbers of economic units, and of prevailing on them to function with less friction and greater harmony.
