'We have long since passed the simple stage of living beyond our incomes. We are engaged in living beyond the incomes of generations to come.' Let me illustrate by a supposititious example. A nation has an expenditure of $100,000,000 a year. It raises the sum by taxation of some sort and thus lives within its means. But $100,000,000 is the interest on a much larger sum, let us say $2,500,000,000. If instead of paying out a hundred million year by year for expenses, we capitalize it, we may have immediately at hand a sum twenty-five times as great. The interest on this sum is the same as the annual expense account. Let us then borrow $2,500,000,000 on which the interest charges are $100,000,000 a year. But while paying these charges the nation has the principal to live on for a generation. Half of it will meet current expenses for a dozen years, and the other half is at once available for public purposes, for dockyards, for wharves, for fortresses, for public buildings and, above all, for the ever-growing demands of military conscription and of naval power. Meanwhile the nation is not standing still. In these twelve years the progress of invention and of commerce may have doubled the national income. There is then still another $100,000,000 yearly to be added to the sum available for running expenses. This again can be capitalized, another $2,500,000,000 can be borrowed, not all at once perhaps, but with due regard to the exigencies of banking and the temper of the people. With repeated borrowings the rate of taxation rises. Living on the principal sets a new fashion in expenditure. The same fashion extends throughout the body politic. Individuals, corporations, municipalities all live on their principal. The purchase of railways and other public utilities by the government tends further to complicate the problems of national debt. It is clear that this system of buying without paying can not go on forever. The growth of wealth and population can not keep step with borrowing, even though all funds were expended for the actual needs of society. Of late years, war preparation has come to take the lion's share of all funds, however gathered, "consuming the fruits of progress." What the end shall be, and by what forces it will be brought about, no one can now say. This is still a very rich world, even though insolvent and under control of its creditors. There is a growing unrest among taxpayers. There would be a still greater unrest if posterity could be heard from, for it can only save itself by new inventions and new exploitations or by frugality of administration of which no nation gives an example to-day.
