[2] In measuring labor we, of course, take account of the quality of the men who perform it, and the work of a skillful man is counted as more units of labor than that of an unskillful one.
CHAPTER VIII
WAGES
The Equilibrium of Industrial Groups.—The different industrial groups are in equilibrium when they attract labor and capital equally, and that occurs when these agents produce as much per unit employed in one group as in another. Such equalized productivity is the bottom fact of a static condition, and equalized pay follows from it. Wages and interest tend to be uniform in all the groups. Efficient labor, of course, gets in any employment more than inefficient; but labor of a given grade gets in all the groups that make up industrial society a uniform rate of pay, and nothing is to be gained by any capitalist or by any laborer by moving from one employment to another. They all therefore stay where they are, not because they cannot move freely if they wish to do so, but because no inducement to move is offered to them. This is a condition of perfect mobility without motion—of atoms ready to move at a touch without the touch that would move them. The paradox indeed holds that it is the ideally perfect mobility which has existed in the past which positively excludes motion in the present. At some time in the past labor and capital have gone from group to group till they have brought about an adjustment in which they have no incentive for moving farther. The surface of a pool of water is kept tranquil, not because the water is not perfectly fluid, but because, in spite of the fact that it can flow with entire freedom in any direction if it is impelled more in that direction than in any other, each particle of it is impelled equally in all directions. It is the perfect equilibrium that keeps the particles from changing their places, and fluidity has caused the equilibrium. In like manner when labor and capital can create and get just as much in one place as in another, they are attracted as strongly in one direction as in another and therefore do not move. A young man of average capacity, who is deliberating upon the choice of an occupation, will find that he can do as well in a cotton mill as he can in a shoe factory, a machine shop, a lumber mill, a flouring mill, or any other industrial establishment requiring his particular grade of capacity. This is the picture of a perfectly static industrial condition. Economic science has to account for values, wages, and interest as they would be in such a condition, however impossible it is that society should ever reach exactly such a state. The values, wages, and interest in a real market are forever tending toward the rates that would be established if the static condition were realized.
The Sign of a Static State.—The sign of the existence of a static condition is, therefore, that labor and capital, though they are perfectly free to move from one employment to another and would actually do so on the slightest inducement, still do not move. They stay where they are because they cannot find places where they can produce the slightest amount in excess of what they now produce, and no employer will anywhere offer any excess above the prevailing rate of pay.
Profits and the Movements they induce the Sign of a Dynamic State.—Entrepreneur's profits, when they exist, mean that this equilibrium is disturbed, and when it is so, mobility of labor and capital affords the guaranty that a new equilibrium will be established if no further disturbances follow. As we have said, profits attract labor and capital, increase the output of those goods which yield the profit, and reduce the prices of them to the no-profit level. Workmen and capitalists then get from the entrepreneur as wages and interest all that he gets from the public as the price of his goods, except what he pays for raw materials.[1] In other words, the employer sells his goods at cost.
How Costs are Determined.—The early studies of "natural" values, or values which conform to costs of production, were unconscious and imperfect attempts to attain the laws of value in a static state. In such a state costs resolve themselves into wages and interest, and the conception of such a static state is therefore not complete unless we know how wages and interest themselves are determined. What we have already said implies that they fluctuate about certain standards, just as do the prices of goods, and that they would remain at these standards if society were reduced to a static condition.
Significance of Static Law in a Dynamic State.—An actual society is undergoing constant disturbances. It is very far from being static; and yet values of goods, on the one hand, and the earnings of labor and capital, on the other, hover within a certain distance of the standards which would be realized if the society became static. In spite of active dynamic movements the general returns of labor and capital can never range so far from these theoretical amounts that the distance from them cannot in some way be measured and accounted for. The sea, when gales are blowing and tides are rising and falling, is anything but a static object, and yet it keeps a general level in spite of storms and tides, and the surface of it as a whole is surprisingly near to the ideal mathematical surface that would be presented if all disturbances were to cease. In like manner there are certain influences that are disturbing the economic equilibrium just as storms and tidal waves disturb the equilibrium of the sea. We cannot actually stop these influences any more than we can stay the winds and the lunar attraction; but we can create an imaginary static state for scientific purposes, just as a physicist by a process of calculation can create a hypothetical static condition of the sea and discover the level from which heights and depths should be measured. No more than the economist can he actually bring the subject he is dealing with to a motionless condition. The economic ocean will defy any modern Canute who may try to stop its movements; but it is necessary to know what shape and level it would take if this were done.
