Not only are corporation, business, license and similar taxes being 159 developed, but increasing resort is had to inheritance taxes, over thirty states now making use of this form of taxation. They are more frequently imposed on collateral than direct inheritances, and in many states are progressive, both as to amount and as to nearness of relationship. Thus in Wisconsin the rates advance from one per cent for bequests under $25,000 to husband, wife, or lineal relation, to 15 per cent for sums over $500,000 to very distant relatives or strangers. These various forms of taxation are necessary to secure the needed revenues for the state governments, especially if these forego further resort to taxation of realty. The tendency is now sufficiently marked to make it possible to indicate with some certainty the future of taxation in this country. To a certain extent, however, this must be regarded as the expression of an ideal rather than the description of an existing system. The Federal Government should have customs and excise duties, supplemented by an income tax. The state governments should have corporation and inheritance taxes. The cities and minor civil divisions should have taxes on realty, and license and franchise taxes. Such a division is logical and avoids duplication of taxation of the same source by two or more grades of government. In view of the pre-emption of the field of corporation taxation by the states, it is therefore doubly regrettable that the Federal Government should now (August, 1909) have adopted a tax on income of corporations for federal purposes.
Other problems connected with finance are suggested in connection with the universal tendency to increase in governmental expenditures and in public debts. The former is an expression of the growth and expansion of state functions, which will be discussed in the next section. The latter is due in part to this same fact, in part also to the development of credit and the creation of a market for the sale of 160 public and other securities, and finally to the growth of constitutional government, which has made the people willing to entrust their capital to a government which they themselves as citizens really control.
