Fiscal policy primarily aims to influence the economy through adjustments in government spending and taxation. When the government decides to spend more money on things like roads, schools, or healthcare, it can help create jobs and boost economic activity. Conversely, if the government raises taxes, it can slow down spending by individuals and businesses, which might help control inflation. However, when the government consistently spends more than it collects in taxes, it can lead to an increase in national debt. For example, if a country spends a lot on infrastructure projects but does not raise taxes to cover those costs, it may borrow money, which increases its national debt.
