4. _Continuing profits arise from the continued exercise of superior judgment._ After all the chance elements are taken into account, there remain differences in the abilities of men, and a continued and ever-renewed need of organizing power. Profits, being recognized as due to these differences in the abilities just as rent is due to differences in the fertility and efficiency of goods, have therefore been called differential gains. There would be no objection to the term were it not intended to emphasize a supposed difference between profits and rents on the one hand and interest wages on the other. [Sidenote: Risk of loss reduced by skill] Some writers have so magnified the thought that the enterpriser's function is to assume risk, as to make it a denial of the view that profits are the earnings of ability. The risks of business are not those of the throwing of dice in which (if it is fair) skill plays no part, and gains in the long run offset losses. Business risks are rather those of the rope-walker in crossing Niagara; the task is easily undertaken by the skilful Blondin, it is fatally dangerous to the man of unsteady nerve and limb. Profits are due not to risks, but to superior skill in taking risks. They are not subtracted from the gains of labor but are earned, in the same sense in which the wages of skilled labor are earned. So long as some men have better organizing ability than others, have better judgment, are better able to take the risks, there is reason to believe that profits will continue. Profits are the share, or income, of the enterpriser for his skill in directing industry and in assuming the risks. Despite the complex influences, they are determined by his contribution to industry essentially as is the value of any skilled service. CHAPTER 32 PROFIT-SHARING, PRODUCERS' AND CONSUMERS' COÖPERATION § I. PROFIT-SHARING [Sidenote: Nature and definition of profit-sharing] 1. _Profit-sharing is rewarding labor with a share of the profits in addition to contract wages._ The essential mark of profit-sharing is that the additional payment depends on the net profits of the whole business at the end of the year. It is not to be confused with a free gift, or with special privileges granted by the employer, such as lunch-rooms, bathrooms or houses at a low rent. Profit-sharing is a contract made in advance, not a free gift. Nor is it the same as a bonus or premium for a larger output, made contingent on the physical product, on the increased number of pieces turned out by the workmen, individually or in groups. Premium for output is given for something directly under the influence of the worker. The amount of profits is affected by the amount of output, but also by a number of other things that are quite outside the control of the workmen. [Sidenote: The possibilities of profit-sharing]
