Social Security was created in 1934 by President Roosevelt to provide financial assistance to unemployed, elderly, and disabled individuals. It was later expanded to include cost of living adjustments in 1972 and health benefits through Medicare and Medicaid. Over time, payroll tax rates for Social Security have increased to fund promised benefits. However, as millions of baby boomers retire over the next 10 years, the program's annual surplus will shrink and disappear, requiring billions in additional funding by around 2017 to pay all promised benefits.
