Adam Smith analysed the process of industry in which he found the community of his time engaged, and found the three classes of agents or factors: Land, Labor, and Capital (stock). The productive factors engaged being thus determined, the norm of natural-economic equivalence and equity already referred to above, indicated what would be the natural sharers in the product. Later economists have shown great reserve about departing from this three-fold division of factors, with its correlated three-fold division of sharers of remuneration; apparently because they have retained an instinctive, indefeasible trust in the law of economic equivalence which underlies it. But circumstances have compelled the tentative intrusion of a fourth class of agent and income. The undertaker and his income presently came to be so large and ubiquitous figures in economic life that their presence could not be overlooked by the most normalising economist. The undertaker's activity has been interpolated in the scheme of productive factors, as a peculiar and fundamentally distinctive kind of labor, with the function of coördinating and directing industrial processes. Similarly, his income has been interpolated in the scheme of distribution, as a peculiar kind of wages, proportioned to the heightened productivity given the industrial process by his work.[4] His work is discussed in expositions of the theory of production. In discussions of his functions and his income the point of the argument is, how and in what degree does his activity increase the output of goods, or how and in what degree does it save wealth to the community. Beyond his effect in enhancing the effective volume of the aggregate wealth the undertaker receives but scant attention, apparently for the reason that so soon as that point has been disposed of the presence of the undertaker and his income has been reconciled with the tacitly accepted natural law of equivalence between productive service and remuneration. The normal balance has been established, and the undertaker's function has been justified and subsumed under the ancient law that Nature does all things well and equitably.

This holds true of the political economy of our grandfathers. But this aim and method of handling the phenomena of life for theoretical ends, of course, did not go out of vogue abruptly in the days of our grandfathers.[5] There is a large sufficiency of the like aim and animus in the theoretical discussions of a later time; but specifically to cite and analyse the evidence of its presence would be laborious, nor would it conduce to the general peace of mind.

Some motion towards a further revision of the scheme is to be seen in the attention which has latterly been given to the function and the profits of that peculiar class of undertakers whom we call speculators. But even on this head the argument is apt to turn on the question of how the services which the speculator is conceived to render the community are to be construed into an equivalent of his gains.[6] The difficulty of interpretation encountered at this point is considerable, partly because it is not quite plain whether the speculators as a class come out of their transactions with a net gain or with a net loss. A systematic net loss, or a no-profits balance, would, on the theory of equivalence, mean that the class which gets this loss or doubtful gain is of no service to the community; yet we are, out of the past, committed to the view that the speculator is useful—indeed economically indispensable—and shall therefore have his reward. In the discussions given to the speculator and his function some thought is commonly given to the question of the "legitimacy" of the speculator's traffic. The legitimate speculator is held to earn his gain by services of an economic kind rendered the community. The recourse to this epithet, "legitimate," is chiefly of interest as showing that the tacit postulate of a natural order is still in force. Legitimate are such speculative dealings as are, by the theorist, conceived to serve the ends of the community, while illegitimate speculation is that which is conceived to be disserviceable to the community.

The theoretical difficulty about the speculator and his gains (or losses) is that the speculator ex professo is quite without interest in or connection with any given industrial enterprise or any industrial plant. He is, industrially speaking, without visible means of support. He may stake his risks on the gain or on the loss of the community with equal chances of success, and he may shift from one side to the other without winking.

The speculator may be treated as an extreme case of undertaker, who deals exclusively with the business side of economic life rather than with the industrial side. But he differs in this respect from the common run of business men in degree rather than in kind. His traffic is a pecuniary traffic, and it touches industry only remotely and uncertainly; while the business man as commonly conceived is more or less immediately interested in the successful operation of some concrete industrial plant. But since the undertaker first broke into economic theory, some change has also taken place as regards the immediacy of the relations of the common run of undertakers to the mechanical facts of the industries in which they are interested. Half a century ago it was still possible to construe the average business manager in industry as an agent occupied with the superintendence of the mechanical processes involved in the production of goods or services. But in the later development the connection between the business manager and the mechanical processes has, on an average, grown more remote; so much so, that his superintendence of the plant or of the processes is frequently visible only to the scientific imagination. That activity by virtue of which the undertaker is classed as such makes him a businessman, not a mechanic or foreman of the shop. His superintendence is a superintendence of the pecuniary affairs of the concern, rather than of the industrial plant; especially is this true in the higher development of the modern captain of industry. As regards the nature of the employment which characterises the undertaker, it is possible to distinguish him from the men who are mechanically engaged in the production of goods, and to say that his employment is of a business or pecuniary kind, while theirs is of an industrial or mechanical kind. It is not possible to draw a similar distinction between the undertaker who is in charge of a given industrial concern, and the business man who is in business but is not interested in the production of goods or services. As regards the character of employment, then, the line falls not between legitimate and illegitimate pecuniary transactions, but between business and industry.

The distinction between business and industry has, of course, been possible from the beginning of economic theory, and, indeed, the distinction has from time to time temporarily been made in the contrast frequently pointed out between the proximate interest of the business man and the ulterior interest of society at large. What appears to have hindered the reception of the distinction into economic doctrine, is the constraining presence of a belief in an order of Nature and the habit of conceiving the economic community as an organism. The point of view given by these postulates has made such a distinction between employments not only useless, but even disserviceable for the ends to which theory has been directed. But the fact has come to be gradually more and more patent that there are constantly, normally present in modern economic life an important range of activities and classes of persons who work for an income but of whom it cannot be said that they, either proximately or remotely, apply themselves to the production of goods. Their services, proximate or remote, to society are often of quite a problematical character. They are ubiquitous, and it will scarcely do to say that they are anomalous, for they are of ancient prescription, they are within the law and within the pale of popular morals.

Of these strictly economic activities that are lucrative without necessarily being serviceable to the community, the greater part are to be classed as "business." Perhaps the largest and most obvious illustration of these legitimate business employments is afforded by the speculators in securities. By way of further illustration may be mentioned the extensive and varied business of real-estate men (land-agents) engaged in the purchase and sale of property for speculative gain or for a commission; so, also, the closely related business of promoters and boomers of other than real-estate ventures; as also attorneys, brokers, bankers, and the like, although the work performed by these latter will more obviously bear interpretation in terms of social serviceability. The traffic of these business men shades off insensibly from that of the bona fide speculator who has no ulterior end of industrial efficiency to serve, to that of the captain of industry or entrepreneur as conventionally set forth in the economic manuals.

The characteristic in which these business employments resemble one another, and in which they differ from the mechanical occupations as well as from other non-economic employments, is that they are concerned primarily with the phenomena of value—with exchange or market values and with purchase and sale—and only indirectly and secondarily, if at all, with mechanical processes. What holds the interest and guides and shifts the attention of men within these employments is the main chance. These activities begin and end within what may broadly be called "the higgling of the market." Of the industrial employments, in the stricter sense, it may be said, on the other hand, that they begin and end outside the higgling of the market. Their proximate aim and effect is the shaping and guiding of material things and processes. Broadly, they may be said to be primarily occupied with the phenomena of material serviceability, rather than with those of exchange value. They are taken up with phenomena which make the subject matter of Physics and the other material sciences.

The business man enters the economic life process from the pecuniary side, and so far as he works an effect in industry he works it through the pecuniary dispositions which he makes. He takes thought most immediately of men's convictions regarding market values; and his efforts as a business man are directed to the apprehension, and commonly also to the influencing of men's beliefs regarding market values. The objective point of business is the diversion of purchase and sale into some particular channel, commonly involving a diversion from other channels. The laborer and the man engaged in directing industrial processes, on the other hand, enter the economic process from the material side; in their characteristic work they take thought most immediately of mechanical effects, and their attention is directed to turning men and things to account for the compassing of some material end. The ulterior aim, and the ulterior effect, of these industrial employments may be some pecuniary result; work of this class commonly results in an enhancement, or at least an alteration, of market values. Conversely, business activity may, and in a majority of cases it perhaps does, effect an enhancement of the aggregate material wealth of the community, or the aggregate serviceability of the means at hand; but such an industrial outcome is by no means bound to follow from the nature of the business man's work.

From what has just been said it appears that, if we retain the classical division of economic theory into Production, Distribution, and Consumption, the pecuniary employments do not properly fall under the first of these divisions, Production, if that term is to retain the meaning commonly assigned to it. In an earlier and less specialised organisation of economic life, particularly, the undertaker frequently performs the work of a foreman or a technological expert, as well as the work of business management. Hence in most discussions of his work and his theoretical relations his occupation is treated as a composite one. The technological side of his composite occupation has even given a name to his gains (wages of superintendence), as if the undertaker were primarily a master-workman. The distinction at this point has been drawn between classes of persons instead of between classes of employments; with the result that the evident necessity of discussing his technological employment under production has given countenance to the endeavor to dispose of the undertaker's business activity under the same head. This endeavor has, of course, not wholly succeeded.
