Answer:
The authors of the Federalist Papers felt that the central, Federal government should be stronger than state governments. They felt that the Federal government should be have the power to tax citizens, establish a US currency to be used in all the states, and pass laws that apply to all states. They were reacting to the Articles of Confederation, the first US "constitution" that gave most power to the states leaving the Federal government weak. So weak in fact that it had no authority to settle disagreements between states, could not tax citizens to pay debts from the revolutionary war, and could not establish a common currency, all of which led to much civil unrest (see Shay's Rebellion)
