_The Merging of Functions Desirable._--The uniting in one person of the functions of capitalist, laborer, and _entrepreneur_ contributed much to the productivity of the small-shop system of former days. The man who had a few thousand dollars invested in a little shop and employed a few men to assist him got three different kinds of income, and the sum of the three was larger than anything he could have secured if he had been only a laborer or only a small capitalist and _entrepreneur_. He worked harder and more intelligently than a hired superintendent would have done; he was led to be cautious because his own capital was risked in his business, and yet he was spurred to enterprise by the fact that when, by virtue of the influences which we call _dynamic_, profits were made, he got them. Even in the largest corporations the same conditions contribute to success, and it is best that managers should be owners of some part of the capital which they handle and receivers of some portion of the profits which they try to secure for their companies. Where competition is sharp, companies directed by their owners may supplant those of which the direction is given over to hired managers. The growth of corporations does, however, tend to put salaried men more and more into controlling positions and to reduce the power of the body of stockholders, who perform a joint function as capitalists and _entrepreneurs_. In itself this tends to reduce profits and detracts from the advantages which the incorporation of a business offers.
