There are several restrictions on large-scale production, one or two of which we may profitably examine at this point. First of all, any industry is likely to grow so large as to become unwieldy. Such an industry is no longer the "child" of the one who developed it. It is now impersonal. Consequently, its administration and management is divided among hired superintendents: each ambitious to develop his own department; each more or less selfish in his attitude toward the whole industry; and none with the keen interest of the owners of smaller plants. When a unit of industry reaches this stage in the development of large-scale production, it is likely to be less efficient than smaller ones in the same line of business. Such industries resemble in many respects the overgrown trees of the forest, towering above their fellows in height, but rotten at the heart and exposed to every passing storm.
