this reason, viz., that when both capitalist and laborer are interested in the risks and results of an enterprise, the enterprise will then have the benefit of two heads, instead of one, in judging of its feasibility and probable results, and also in deciding upon the best plan of execution. Injudicious enterprises will then be more likely to be avoided; and less labor and capital will, therefore, be wasted on such enterprises than now are. When a capitalist loans money to a laborer, and knows that he will have a claim on the subsequent earnings of the laborer for any capital that may be sunk in the enterprise, he (the capitalist) does not look, for himself, into the merits of the enterprise as he would if he knew that his ultimate security for his capital depended solely upon the success of the enterprise, instead of depending also upon the subsequent earnings of the laborer.
