4. _The experience with these plans verifies the analysis of the enterpriser's function: pure profits are the earnings of a productive service._ Comparing these three plans, they are seen to be alike in seeking to make workers share some of the profits, to change the destination to which profits would go. The first would create profits by the effort of the workers, and give them a part of the saving. The second would have collective workers perform the enterpriser's work in the factory and get his reward. The third would have collective buyers do the work of the merchant and save his profits and other costs. The last is the easiest to do. Profit-sharing is next in difficulty, and producers' coöperation is the hardest of all to put into practice. In some cases, under some conditions, the enterpriser's services may be more economically performed than at present, for the waste is great. But taking men as they are and things as they are, in most places the enterpriser's service is necessary and must be paid for. His contribution to the success of the industry depends on his nature and ability, and it can be distinguished theoretically and practically from the contribution made by the workmen. Nothing but changes in human nature, in education, and in morality can diminish the necessity for his service. CHAPTER 33 MONOPOLY PROFITS § I. NATURE OF MONOPOLY [Sidenote: Difficulty of fixing the meaning of monopoly] 1. _The term monopoly is used loosely and in many senses._ In popular discussion monopoly means almost any wealthy corporation or the power the corporation possesses, a power which is usually thought of as oppressive. Even economists have held the vaguest ideas regarding monopoly. The recent rise of trusts and monopolies has given a large new body of facts bearing upon the subject, but all the resulting discussion by the public and by economists has not brought agreement upon a definition entirely satisfactory. When usage has not settled upon any one meaning, the selection of a definition is in a measure arbitrary, though it may be guided by logic and considerations of expediency. Let us state the various meanings and indicate the one adopted in this discussion. [Sidenote: Monopoly is not merely scarcity]
