Federalist 38: 10
... urged against the new system lie with tenfold weight against the existing Confederation? Is an indefinite power to raise money dangerous in the hands of the federal government? The present Congress can make requisitions to any amount they please, and the States are constitutionally bound to furnish them; they can emit bills of credit as long as they will pay for the paper; they can borrow, both abroad and at home, as long as a shilling will be lent. Is an indefinite power to raise troops dangerous? The Confederation gives to Congress that power also; and they have already begun to make use of it. Is it improper and unsafe to intermix the different powers of government in the same body of men? Congress, a single body of men, are the sole depositary of all the federal powers. Is it particularly dangerous to give the keys of the treasury, and the command of the army, into the same hands? The Confederation places them both in the hands of Congress. Is a bill of rights essential to liberty? The Confederation has no bill of rights. Is it an objection against the new Constitution, that it empowers the Senate, with the concurrence of the Executive, to make treaties which are to be the laws of the land? The existing Congress, without any such control, can make treaties which they themselves have declared, and most of the States have recognized, to be the supreme law of the land. Is the importation of slaves permitted by the new Constitution for twenty years? By the old it is permitted forever.
