through which such varied sources of gratification can be compared.
Gross and net income
4. Income in the logical sense must be a net addition, but the term gross income is not without popular and practical meaning. Gross income is sometimes spoken of in the sense of total receipts, as the total of goods secured; net income is the remainder after deducting expenditures and after replacing the goods employed to secure the income. In order to produce some goods technically, men make use of other goods. While they are storing up a supply of wood or coal it may be looked upon as the income, but they may burn it to help grow hothouse plants. While they gather flowers with one hand, they destroy fuel with the other. Only the net increase in value can be accounted income in the second period. The goods that come into a man's possession in any period are of many sorts: to get some he has destroyed many previously existing goods; while to get others he has not needed to use up the accumulations of the past or to mortgage the future. The one kind is gross, the other net income.
Wealth and income
5. An income of consumption goods is a part of wealth, but not the whole of it. The consumption goods, the "present goods" at the moment available, are the essential part of wealth for the moment's enjoyment. The only essential and immediate conditions of a series of gratifications is a regular series of consumption goods. But many things existing which could be used to secure a gratification are not in fact treated as consumption goods. A crop of corn is not all income. In a time of famine it could be used, but seed-corn was saved from last year, and some must be kept for next year. This is a part of wealth, but not of "present goods" as we understand the term.
Some goods never can become enjoyable goods
Further, in the economic world there is much wealth that never can gratify any want directly; many forms of wealth never can be consumption goods. It is true that everything called wealth is expected to contribute sooner or later in some way to the sum of gratifications. It is for that reason it is called wealth. It is, however, a mere figure of speech to say indirect want-gratifiers become want-gratifying goods. For example, the engine transporting a load of coal is indirectly gratifying wants; if it is transporting a train-load of passengers, the gratification is direct. A machine making cloth for next year is gratifying wants only in a metaphorical sense. A field used to produce food is not a direct want-gratifier until it is transformed into a residence site, a playground, or a tennis-court.
It is necessary therefore to recognize the distinction between present and future incomes. The value of the mass of wealth in possession and yielding income, rests in large part upon its power of contributing to income in some future period. Thus, any durable good may be looked upon as embodying a series of incomes ranging from present to future in varying degrees. This will be fully considered under the subject of capital.
Income from wealth and from labor
6. Incomes are called funded or unfunded according to the sources from which they are derived. Funded income arises from the possession of wealth or of claims on wealth, such as lands, railroad stocks, government bonds, etc. The income is "funded" because it corresponds to an abiding fund of wealth. The income arising from current labor is unfunded, because there is no permanent fund of accumulated wealth corresponding to it.
The idea of regularity connected with funded income is not essential to the idea of income in general, i.e., we cannot refuse to call a thing income because it occurs only this year. If it is part of the sum of goods that flows in, that is newly available for the man's use, it is income. But funded income is the more abiding, for income from wages stops when the man dies or fails to perform his work, while the income from wealth continues after he ceases to be active. Thus, families with equal incomes may differ greatly in wealth, the one depending entirely on salaries, the other on rents.
§ II. INCOME AS A SERIES OF GRATIFICATIONS
Gratification the test of psychic income
All sources of income are productive
1. The value of consumption goods is derived from the pleasurable psychic impressions which they aid to produce, and these psychic effects constitute the psychic income. The objective income is sometimes called the "real" income, but certainly it is not income in the most essential sense. Things outside of men cannot be feelings, they can only call out or occasion feeling, and it is the attainment of pleasurable conditions in mind or soul that is the aim of all economic activity. Material income and immaterial income are both related to and reducible to psychic income. Some portions at least of the objective incomes of goods are continually by use becoming subjective incomes of enjoyment. Men talk of material income as consisting of bushels of wheat, head of cattle, etc., and of immaterial income as the uses that durable goods yield directly or that men perform for each other, e.g., those of the singer, physician, teacher, judge—all services that do not take on material form. There was a long-standing dispute in economic literature regarding the difference between productive and unproductive labor. Productive labor was said to be that which embodied itself in abiding material form. The distinction led to some peculiar puzzles and paradoxes. The bartender mixing drinks, adds to the value of those ingredients; in a minute that value is dissipated. According to the distinction in question, he is a productive laborer because his services are embodied in material form, whereas the lecturer is regarded as an unproductive laborer because the results of his labor are not embodied in material form. But whether or not the service has for a moment embodied itself in material form is of no essential economic import. The presence of the waiter is as essential to the well-served dinner as are the polished silver and china, or as the well-cooked food. The distinction in question is not now made by economists, all labor that contributes to value being regarded as productive. But a similar distinction is inconsistently preserved by many writers in the case of material things. A building used as a factory is called productive, but used by the owner as a dwelling it is called unproductive because the service it renders does not appear in material form. But the use of the house, or that of land for a school ground or campus, secures a certain gratification, an immaterial good. Consistency requires that the services of men and the use of material things be judged by their psychic results, the question whether the service takes on a material or an immaterial form being disregarded.
All wealth is logically related to psychic income
2. Only those things and actions that are in some causal relation to gratifications can have value to man. This proposition of theory is demonstrated every hour in practical life. The business man always is trying to trace a causal relation between things that do not and cannot themselves directly satisfy wants, and things that do. The vineyard has no value to Tantalus, unable to reach its fruit. A captive, chained to a rock, attaches value only to the things within his reach. Men living in savagery and ignorance starve amid the possibilities of plenty. Chained by their ignorance and improvidence to a little spot of earth, they do not see clearly, either in time or space, the economic relations about them.
Values of things distant in time
3. Man's foresight and knowledge enable him to think of many periods at once, and thus his felt dependence on goods extends over a series of future productive agents. In order to simplify the problem, we have spoken of the economic man as living only in and for the moment. If he had no more knowledge, memory, or imagination than is necessary to compare goods here, only present goods could have value to him. Even the higher animals, and much more the savages, rise above that level of improvidence. With increased intelligence the economic life of man expands, and he attaches importance to things which at the present moment have not, and cannot have, the slightest influence on his immediate gratification. The extension of man's view works a momentous change in his economic estimates. Of the thousands of forms of matter in the world, only a comparatively few ever will make an immediate gratifying impression on man's senses. But many of them are so connected in his thought by chains of association with pleasures or uses, that almost instinctively and most intensely he attaches an importance to them. In most cases it would require close thought to see that the service attributed directly to them was but a reflection of that performed by some other good. Thus, more and more, the estimates placed by men on goods come to depend on knowledge and foresight,
