There is a machine used for sizing the cotton yarn to prepare it for weaving, by which it is dried over a steam cylinder, the wages for attendance on which were only two dollars per day, as compared with an expenditure for labor of fourteen dollars per day to accomplish the same ends before the machine was invented. All attempts to make out that the laboring-classes as a collective body _can not_ suffer temporarily by the introduction of machinery, or by the sinking of capital in permanent improvements, are, I conceive, necessarily fallacious.(111) That they would suffer in the particular department of industry to which the change applies is generally admitted, and obvious to common sense; but it is often said that, though employment is withdrawn from labor in one department, an exactly equivalent employment is opened for it in others, because what the consumers save in the increased cheapness of one particular article enables them to augment their consumption of others, thereby increasing the demand for other kinds of labor. This is plausible, but, as was shown in the last chapter, involves a fallacy; demand for commodities being a totally different thing from demand for labor. It is true, the consumers have now additional means of buying other things; but this will not create the other things, unless there is capital to produce them, and the improvement has not set at liberty any capital, even if it has not absorbed some from other employments. If the improvement has lowered the cost of production, it has often required less capital (as well as less labor) to produce the same quantity of goods; or, what is the same thing, an increased product with the same capital. § 3. —This seldom, if ever, occurs. Nevertheless, I do not believe that, as things are actually transacted, improvements in production are often, if ever, injurious, even temporarily, to the laboring-classes in the aggregate. They would be so if they took place suddenly to a great amount, because much of the capital sunk must necessarily in that case be provided from funds already employed as circulating capital. But improvements are always introduced very gradually, and are seldom or never made by withdrawing circulating capital from actual production, but are made by the employment of the annual increase. I doubt if there would be found a single example of a great increase of fixed capital, at a time and place where circulating capital was not rapidly increasing likewise. In the United States, while the cost per yard of the manufactured goods has decreased, and so made accessible to poorer classes than before, the capital engaged in manufactures has increased so as to allow a vastly greater number of persons to be employed, as will be seen by the following comparison of 1860 with 1880 taken from the last census returns.
