The revolution caused by the introduction of machines in one branch of industry necessitated its introduction into another, etc. The means of communication and of transportation were extended. The steamboat, the railroad, and the telegraph were invented. Because of important inventions in the manufacture of machines it finally became possible to produce the necessary quantity of machines of all kinds.

What are the most important consequences of the new system of production? In the first place stands the introduction of the labor of women and children, since tending machines generally does not require great muscular strength. The advantages which accrue to the capitalist from the employment of women and children are obvious. Since the price of the workman’s labor is determined by the time necessary for the production of the necessities of life not only for [[256]]himself, but also for his family, as soon as the whole family are compelled to sell their labor, the price of that labor will simply equal that of the labor of the workman alone. Ordinarily the income of the family will rise a little under these circumstances, but, because of the absence of the wife from the household, expenses will increase also. The increase of the surplus-value, obtained by the labor of women and children, is therefore important. Besides, the women and children have less power to resist the capitalist than men have, while the men, in their turn, are weakened by the competition of women and children.

In the second place the introduction of machines produces in the mind of the capitalist a desire to prolong the working day as much as possible, for the following reasons among others. The greater the number of hours each day in which the machine is in operation, the more quickly it will return its cost through the product, and, other things being equal, the shorter will be the time required for the capitalist to gain the same amount of surplus-value. Suppose A works his machines for 8 hours a day, and B works as many machines for 16 hours; B’s machines will return their cost through the product in half the time needed by A’s. Consequently B will gain double the surplus-value in the same time, so that A also will be driven to work his machines for 16 hours. And since a machine deteriorates even when it is not in use, there is, when the machines are stopped, a loss of value which the capitalist cannot retrieve. Hence the tendency to prolong the working-day. In the third place every capitalist runs the danger of seeing his competitors introduce new machines which save still more work and so diminish the value of his own. The more quickly a machine returns its cost, the less the danger just mentioned becomes.

Finally, I have still to notice the following cause for the prolongation of the working-day. The object of the employment of machines is the increase of the surplus-value through their use. This increase, however, is possible only through the diminution in the number of workmen employed by the capitalist. But since the surplus-value is created only by the workmen, any diminution in their number is to the disadvantage of the capitalist. In order to overcome this he attempts to prolong the day.

The more machinery is developed, the more the attention which the workman must give to his work increases; in other words, the more intense the labor becomes. The tendency of the capitalist to increase the intensity of labor reaches its apogee as soon as the working time is limited, for different reasons. In order that the surplus-value may [[257]]be equal to what it was formerly, the workman, for example, must produce as much in eleven hours as he formerly produced in thirteen hours. The means by which the intensity of labor is increased (not to enter into unnecessary details) are; first, the manner of fixing wages—piece-work, and second, the practice of making the workmen tend more machines than formerly, and of driving the machines faster, so as to force the workmen to a greater intensity of labor.

The contest between the large manufacturing establishments and the small factories and workshops has led gradually but infallibly to the destruction of the latter. They are forced to maintain the competitive struggle by incredibly long hours of labor, by an unlimited exploitation of the labor of women and children, etc. In this way it is often possible to resist competition for some time, but finally the large manufactory triumphs all along the line.

Agriculture also, though to a less degree than manufacturing, has been revolutionized by the introduction of machines. Rural workers who have become superfluous have betaken themselves to the cities, and there go to swell the population already enormously increased by industrialism.

The exposition which I have just given of the origin of the surplus-value is sufficient for this work. It is not necessary for our subject to stop to consider the fact that a part of the surplus-value is destined to become capital, while the other part is consumed by those who have appropriated the whole. As has been shown above, the employment of machines, etc., has increased in every branch of industry, and this has brought it about that the capital necessary to any manufacturing establishment increases continually under the pressure of competition. Hence it follows that capitalism itself forces the capitalist to invest as new capital part of the surplus-value acquired by him. But aside from this, it is capitalism also that produces the capitalist’s penchant for always investing more capital, which, in its turn, produces a greater surplus-value than the original capital, etc. And since the accumulation of capital has no limits, the greediness of the capitalist has none, and he is driven to increase his capital incessantly, even when his income is so great that it permits him to satisfy every possible need.

However, the group of capitalists of which we have been speaking is not the only one that gains surplus-value. Industrial capital is obliged to share the total surplus-value with commercial capital, the capital consisting of money, and that consisting of real estate. In the first place, a part of the surplus-value is claimed by commercial [[258]]capital. For the economic system in force would not be able to operate without commerce. The development of capitalism has led to an extensive division of labor in the class of capitalists (banks, insurance companies, etc.), and the capital invested in these enterprises must equally have its share of the total surplus-value. Capital in the form of money plays an increasingly important part in modern capitalism, and so must have its share of the surplus-value.

The owners of the soil also appropriate a considerable part. The land is the most indispensable means of production, and is incapable of being increased at will. As capitalism increases, the demand for territory becomes greater and greater. This causes the ground rents in general to rise, which means that the share of the total surplus-value which the land-owners appropriate becomes greater and greater. It is especially in the cities, which are highly developed under capitalism, and in which, consequently, the demand for land is great and the supply relatively small, that ground rents have risen to an unheard of degree, and this to the prejudice of the health and happiness of the less privileged classes.
