1. _The men actually in control of industry have been selected in manifold ways._ Skill develops a small industry into a large one. A small factory owner gradually adds machine to machine, building to building, till he finds himself at the head of a great industry. Or an employee develops ability and becomes an employer. Who does not know of some one who, as a small boy, went into a store to do chores, worked up to a clerkship and, enlisting the confidence of men of wealth, was enabled to establish a business of his own and become an employer? Others have won promotion from the ranks to the head of a large industry in which they secured at last a controlling interest. Employees that have proved their ability may be selected by the directors of a stock company. Men that have worked their way up from the ranks may bequeath their business positions to their sons and grandsons, as in the case of the Vanderbilts and the Goulds. And finally, but rarely, there may be selection by fellow-workmen in the case of coöperative business. [Sidenote: Success as the evidence of ability] 2. _There is a constant selective process: dropping out the weak and advancing the efficient organizer._ There is, to be sure, an element of chance in this selection. The process in general is a rude one. Accidents and unforeseen changes, industrial crises, failure of health at a critical moment, fraud and crime, may defeat men of ability and they may never regain their foothold. Lack of experience may lead to disaster a naturally able but youthful heir, too suddenly burdened with the responsibilities of a fortune. On the other hand, men of limited ability may inherit fortunes and preserve them by caution, without enterprise. It is not always true, even in America, that "It is but three generations from shirt-sleeves to shirt-sleeves," although many fortunes slip away from the sons of rich fathers. In general, success in retaining the control of a business is an evidence of considerable ability. By loss of fortune unwisely risked, through unforeseen changes in methods, and after manifold blunders, the less capable drop out. Thus, by the ceaseless working of competition, the higher places are taken by those most capable of filling them, and the efficiency both of the employers and of the workmen is increased.
