Read the following excerpt from Federalist #44 by James Madison. Had every State a right to regulate the value of its coin, there might be as many different currencies as States, and thus the [trade] among them would be impeded; [unexpected changes] in its value might be made, and thus the citizens of other States be injured, and animosities be kindled among the States themselves. The subjects of foreign powers might suffer from the same cause, and hence the Union be discredited and embroiled by the indiscretion of a single member.
James Madison would most likely agree with the idea that
state governments should be stronger than a national government.
foreign governments should have influence on state economies.
each state should regulate its own trade with other countries.
a national government should be supreme over state governments.
