The national budget serves as a financial blueprint for a nation's government, detailing projected revenues and expenditures for fiscal years. It plays a crucial role in politics by determining how public funds are allocated to various programs, such as healthcare, education, and defense. The budget reflects governmental priorities and policy goals, affecting economic growth and social services. Moreover, it influences political debates and decisions, as lawmakers negotiate over funding levels, tax policies, and spending priorities, ultimately shaping the nation's economic landscape and public welfare.
