The Wealth of Nations_ Books 4-5 - Adam Smith [326]
The system of taxation established in those different countries, it may be said, is inferior to that of England. I believe it is so. But it ought to be remembered that, when the wisest government has exhausted all the proper subjects of taxation, it must, in cases of urgent necessity, have recourse to improper ones. The wise republic of Holland has upon some occasions been obliged to have recourse to taxes as inconvenient as the greater part of those of Spain. Another war begun before any considerable liberation of the public revenue had been brought about, and growing in its progress as expensive as the last war, may, from irresistible necessity, render the British system of taxation as oppressive as that of Holland, or even as that of Spain. To the honour of our present system of taxation, indeed, it has hitherto given so little embarrassment to industry that, during the course even of the most expensive wars, the frugality and good conduct of individuals seem to have been able, by saving and accumulation, to repair all the breaches which the waste and extravagance of government had made in the general capital of the society. At the conclusion of the late war, the most expensive that Great Britain ever waged, her agriculture was as flourishing, her manufacturers as numerous and as fully employed, and her commerce as extensive as they had ever been before. The capital, therefore, which supported all those different branches of industry must have been equal to what it had ever been before. Since the peace, agriculture has been still further improved, the rents of houses have risen in every town and village of the country – a proof of the increasing wealth and revenue of the people; and the annual amount of the greater part of the old taxes, of the principal branches of the excise and customs in particular, has been continually increasing – an equally clear proof of an increasing consumption, and consequently of an increasing produce which could alone support that consumption. Great Britain seems to support with ease a burden which, half a century ago, nobody believed her capable of supporting. Let us not, however, upon this account rashly conclude that she is capable of supporting any burden, nor even be too confident that she could support, without great distress, a burden a little greater than what has already been laid upon her.
When national debts have once been accumulated to a certain degree, there is scarce, I believe, a single instance of their having been fairly and completely paid. The liberation of the public revenue, if it has ever been brought about at all, has always been brought about by a bankruptcy; sometimes by an avowed one, but always by a real one, though frequently by a pretended payment.
The raising of the denomination of the coin has been the most usual expedient by which a real public bankruptcy has been disguised under the appearance of a pretended payment. If a sixpence, for example, should either by act of parliament or royal proclamation be raised to the denomination of a shilling, and twenty sixpences to that of a pound sterling, the person who under the old denomination had borrowed twenty shillings, or near four ounces of silver, would, under the new, pay with twenty sixpences, or with something less than two ounces. A national debt of about a hundred and twenty-eight millions, nearly the capital of the funded and unfunded debt of great Britain, might in this manner be paid with about sixty-four millions of our present money. It would indeed be a pretended payment only, and the creditors of the public would really be defrauded of ten shillings in the pound of what was due to them. The calamity, too, would extend much further than to the creditors of the public, and those of every private person would suffer a proportionable loss; and this without any advantage, but in most cases with a great additional loss, to the creditors of the public. If the creditors of the public, indeed, were generally much in debt to other people, they might
