Profit may be increased by economy of operation resulting from large-scale production, by economies in use of by-products, by the standardization of product and improvement of quality, and by the elimination of duplicate effort; or the control of sources of supplies or of a marketing organization, or greater ease in obtaining capital, or greater facility in dealing with labor, may be among the advantages obtained. ”
