"At every stage in the growth of that debt the nation has set up the same cry of anguish and despair. At every stage in the growth of that debt it has been seriously asserted by wise men that bankruptcy and ruin were at hand. Yet still the debt went on growing; and still bankruptcy and ruin were as remote as ever. When the great contest with Louis XIV was finally terminated by the Peace of Utrecht, the nation owed about fifty millions; and that debt was considered, not merely by the rude multitude, not merely by foxhunting squires and coffeehouse orators, but by acute and profound thinkers, as an incumbrance which would permanently cripple the body politic. Nevertheless trade flourished; wealth increased; the nation became richer and richer.
Then came the war of the Austrian Succession; and the debt rose to eighty millions. Pamphleteers, historians and orators pronounced that now, at all events, our case was desperate. Yet the signs of increasing prosperity, signs which could neither be counterfeited nor concealed, ought to have satisfied observant and reflecting men that a debt of eighty millions was less to the England which was governed by Pelham than a debt of fifty millions had been to the England which was governed by Oxford.
Soon war again broke forth; and, under the energetic and prodigal administration of the first William Pitt, the debt rapidly swelled to a hundred and forty millions. As soon as the first intoxication of victory was over, men of theory and men of business almost unanimously pronounced that the fatal day had now really arrived. [...] Not less gloomy was the view which George Grenville, a minister eminently diligent and practical, took of our financial situation. The nation must, he conceived, sink under a debt of a hundred and forty millions, unless a portion of the load were borne by the American colonies.
The attempt to lay a portion of the load on the American colonies produced another war. That war left us with an additional hundred millions of debt, and without the colonies whose help had been represented as indispensable. Again England was given over; and again the strange patient persisted in becoming stronger and more blooming in spite of all the diagnostics and prognostics of State physicians. As she had been visibly more prosperous with a debt of a hundred and forty millions than with a debt of fifty millions, so she, as visibly more prosperous with a debt of two hundred and forty millions than with a debt of a hundred and forty millions.
Soon however the wars which sprang from the French Revolution, and which far exceeded in cost any that the world had ever seen, tasked the powers of public credit to the utmost. When the world was again at rest the funded debt of England amounted to eight hundred millions. [...] It was in truth a gigantic, a fabulous debt; and we can hardly wonder that the cry of despair should have been louder than ever. But again that cry was found to have been as unreasonable as ever. After a few years of exhaustion, England recovered herself. [...] Meanwhile taxation was almost constantly becoming lighter and lighter; yet still the Exchequer was full. It may be now affirmed without fear of contradiction that we find it as easy to pay the interest of eight hundred millions as our ancestors found it, a century ago, to pay the interest of eighty millions. [...]
A long experience justifies us in believing that England may, in the twentieth century, be better able to bear a debt of sixteen hundred millions than she is at the present time to bear her present load. But be this as it may, those who so confidently predicted that she must sink, first under a debt of fifty millions, then under a debt of eighty millions then under a debt of a hundred and forty millions, then under a debt of two hundred and forty millions, and lastly under a debt of eight hundred millions, were beyond all doubt under a twofold mistake. They greatly overrated the pressure of the burden; they greatly underrated the strength by which the burden was to be borne."
