What are the top for programs that federal government spends a large percentage of its funding on?

The federal government allocates a significant portion of its funding to four main programs: Social Security, Medicare, Medicaid, and defense spending. Social Security provides retirement and disability benefits to millions of Americans. Medicare and Medicaid offer health care coverage to the elderly and low-income individuals, respectively. Defense spending encompasses military expenditures and national security initiatives, reflecting the government's commitment to maintaining national security.
