The Increasing Expensiveness of Government.—How- ever crude dependence of governmental finance upon personal borrowing by the sovereign may seem today, it sufficed fairly well for the relatively small needs of sixteenth and seventeenth century governments. In those distant periods populations were smaller than at present, the standard of living was almost inconceivably lower, and the contemporary warfare with blun- derbusses, swords, and sailing ships vastly cheaper. Many a modern city requires vastly more financial accommodation than did the whole kingdom of Elizabeth. Nevertheless, the ex- penses of government were through this period steadily in- creasing, owing to such diverse factors as the Spanish discov- eries of gold in America, the frequent and expensive amours of a Charles or a Louis, and the semireligious, semipolitical wars in the low countries and elsewhere. Financial stringency helped to expel the last Stuart king from England in 1688, and to dampen the warlike ardor of his successor, William III. During the reign of the latter, however, a financial policy was adopted with profound consequences for society. Interest- bearing negotiable certificates acknowledging the public indebt- edness were issued by the State, and sold to the recently created class of English investors who were earnestly seeking a safe way of investing their savings.
