Possibly since the world began, no investment has ever yielded the profit reaped from the Indian plunder, because for nearly fifty years Great Britain stood without a competitor. That she should have so long enjoyed a monopoly seems at first mysterious, but perhaps the condition of the Continent may suggest an explanation. Since Italy had been ruined by the loss of the Eastern trade, she had ceased to breed the economic mind; consequently no class of her population could suddenly and violently accelerate their movements. In Spain the priest and soldier had so thoroughly exterminated the sceptic, that far from centralizing during the seventeenth century, as England and France had done, her empire was in full decline at the revolution of 1688. In France something similar had happened, though in a much less degree. After a struggle of a century and a half, the Church so far prevailed in 1685 as to secure the revocation of the Edict of Nantes. At the revocation many Huguenots went into exile, and thus no small proportion of the economic class, who should have pressed England hardest, were driven across the Channel, to add their energy to the energy of the natives. Germany lacked capital. Hemmed in by enemies, and without a seacoast, she had been at a disadvantage in predatory warfare; accordingly she did not accumulate money, and failed to consolidate until, in 1870, she extorted a treasure from France. Thus, in 1760, Holland alone remained as a competitor, rich, maritime, and peopled by Protestants. But Holland lacked the mass possessed by her great antagonist, beside being without minerals; and accordingly, far from accelerating her progress, she proved unable to maintain her relative rate of advance. Thus isolated, and favoured by mines of coal and iron, England not only commanded the European and American markets, at a time when production was strained to the utmost by war, but even undersold Hindoo labour at Calcutta. In some imperfect way her gains may be estimated by the growth of her debt, which must represent savings. In 1756, when Clive went to India, the nation owed £74,575,000, on which it paid an interest of £2,753,000. In 1815 this debt had swelled to £861,000,000, with an annual interest charge of £32,645,000. In 1761 the Duke of Bridgewater finished the first of the canals which were afterward to form an inland water-way costing £50,000,000, or more than two-thirds of the amount of the public debt at the outbreak of the Seven Years’ War. Meanwhile, also, steam had been introduced, factories built, turnpikes improved, and bridges erected, and all this had been done through a system of credit extending throughout the land. Credit is the chosen vehicle of energy in centralized societies, and no sooner had treasure enough accumulated in London to offer it a foundation, than it shot up with marvellous rapidity.
