§ 940. The states, with this concurrent power, will be entirely sate, and have ample resources to meet all their wants, whatever they may be, although few public expenses, comparatively speaking, will fall to their lot to provide for. They will be chiefly of a domestic character, and affecting internal polity; whereas, the resources of the Union will cover the vast expenditures, occasioned by foreign intercourse, wars, and other charges necessary for the safety and prosperity of the Union. The mere civil list of any country is always small; the expenses of armies, and navies, and foreign relations unavoidably great. There is no sound reason, why the states should possess any exclusive power over sources of revenue, not required by their wants. But there is the most urgent propriety in conceding to the Union all, which may be commensurate by their wants. Any attempt to discriminate between the sources of revenue would leave too much, or too little to the states. If the exclusive power of external taxation were given to the Union, and of external taxation to the states, it would, at a rough calculation, probably give to the states a command of two thirds of the resources of the community, to defray from a tenth to a twentieth of its expenses; and to the Union, one third of the resources of the community, to defray from nine tenths to nineteen twentieths of its expenses. Such an unequal distribution is wholly indefensible. And it may be added, that the resources of the Union would, or might be diminished exactly in proportion to the increase of demands upon its treasury; for (as has been already seen) war, which brings the great expenditures, narrows, or at least may narrow the resources of taxation from duties on imports to a very alarming degree. If we enter any other line of discrimination, it
