If all persons were to expend in personal indulgences all that they produce, and all the income that they receive from what is produced by others, capital could not increase. Some saving, therefore, there must have been, even in the simplest of all states of economical relations; people must have produced more than they used, or used less than they produced. Still more must they do so before they can employ other laborers, or increase their production beyond what can be accomplished by the work of their own hands. If it were said, for instance, that the only way to accelerate the increase of capital is by increase of saving, the idea would probably be suggested of greater abstinence and increased privation. But it is obvious that whatever increases the productive power of labor, creates an additional fund to make savings from, and enables capital to be enlarged, not only without additional privation, but concurrently with an increase of personal consumption. Nevertheless, there is here an increase of saving, in the scientific sense. Though there is more consumed, there is also more spared. There is a greater excess of production over consumption. To consume less than is produced is saving; and that is the process by which capital is increased; not necessarily by consuming less, absolutely. The economic idea of saving involves, of course, the intention of using the wealth in reproduction. Saving, without this meaning, results only in hoarding of wealth, and while hoarded this amount is not capital. To explain the process by which capital comes into existence, Bastiat has given the well-known illustration of the plane in his “Sophisms of Protection.”(107)
