The world has at any given period the power, under existing conditions of production and skill, to create a certain amount of wealth, as represented by the inner rectangle, W. Each increased power of production arising from conquests over Nature’s forces, as the use of steam and labor-saving machinery, permits the total wealth to be enlarged, as, in the figure, to rectangle W’. For the production of wealth are required labor, capital, and land; therefore, if the labor and land are not destroyed by war, there need not necessarily be in existence all the previous capital. If there are the necessaries for all, and only sufficient tools to accomplish the work, they will, in a few years, again recreate all the wealth that formerly existed, regain the same position as before, and go on slowly increasing the total wealth just as fast as improvements in the arts of production render it possible. [Illustration. Inner rectangle W, surrounded by rectangle W’.] § 5. Effects of Defraying Government Expenditure by Loans. [An application of this truth has been made to the question of raising government supplies for war purposes.] Loans, being drawn from capital (in lieu of taxes, which would generally have been paid from income, and made up in part or altogether by increased economy), must, according to the principles we have laid down, tend to impoverish the country: yet the years in which expenditure of this sort has been on the greatest scale have often been years of great apparent prosperity: the wealth and resources of the country, instead of diminishing, have given every sign of rapid increase during the process, and of greatly expanded dimensions after its close. During our civil war, at the same time that wealth was being destroyed on an enormous scale, there was a very general feeling that trade was good, and large fortunes were made. At the close of the war a period of speculation and overtrading continued until it was brought to a disastrous close by the panic of 1873. Much of this speculation, however, was due to an inflated paper currency.
