Answer:
George Washington and Alexander Hamilton's tax policies were unpopular because they introduced taxes for the first time in the United States, and people were not used to the idea of paying taxes. Additionally, they implemented a tax on whiskey production, which was an important industry in the early United States, making the tax very unpopular with the whiskey producers.
Washington and Hamilton believed their tax policies were important because the United States had a large debt after the American Revolutionary War and they needed to find ways to reduce the debt. The taxes on whiskey were intended to raise revenues to reduce the national debt, while the other taxes were introduced to support the new government and provide funding for infrastructure projects such as roads and bridges.
