Final answer:
Hamilton wanted the federal government to assume state debts, which was central to his financial strategy to establish the creditworthiness of the United States and foster economic growth.
Step-by-step explanation:
Hamilton wanted the federal government to promise to pay off state debts. This was part of his plan for economic recovery and growth following the financial strains of the 1780s. By assuming the state debts, Hamilton's strategy was to build loyalty to the national government, reduce taxes at the state level, and thereby avoid the kind of domestic turmoil that had occurred during the previous decade. His proposal also aimed to establish creditworthiness for the United States by demonstrating its commitment to fulfill obligations, which would make the new nation attractive to both domestic and foreign investors.
