Final answer:
The lack of power to collect taxes was a major problem under the Articles of Confederation, leading to difficulties in paying off debt and providing for the country's defense. This weakness in the central government ultimately led to the need for a stronger federal government.
Step-by-step explanation:
One of the biggest problems with the Articles of Confederation was that the national government lacked the power to impose taxes. This meant that the government couldn't collect the necessary funds to pay off the national debt, raise an army, or address threats like Shays's Rebellion. The inability to tax also made it difficult for the government to conduct foreign affairs and protect American ships from attacks. Ultimately, the weak central government created by the Articles of Confederation led to the recognition of the need for a stronger federal government, resulting in the development of the Constitution.
