Some social programs operated by the federal government and often referred to as entitlement programs include Medicare, Social Security, Medicaid and other programs that subsidize certain goods and services for the public. Some of these programs include nutrition assistance and federal unemployment compensation.
Medicare is a federal program that subsidizes medical care for elderly Americans, while Medicaid subsidizes the same service for people of low income who could not otherwise afford health insurance and important health services. Social Security is the large program that includes disability and retirement insurance programs that are paid out to eligible Americans. As of 2015, these programs make up more than 45 percent of the overall federal budget, including a growing share of the U.S. gross domestic product.
