Fact #10: Relatively modest changes would place Social Security on sound financial footing.
Since the mid-1980s, Social Security has collected more in taxes and other income each year than it pays out in benefits and has amassed combined trust funds of $2.8 trillion, invested in interest-bearing Treasury securities. But Social Security’s costs will grow in coming years as baby boomers retire.
The trustees estimate that, if policymakers took no further action, Social Security’s combined Old-Age and Survivors Insurance (OASI) and Disability Insurance trust funds will be exhausted in 2034. After 2034, even if policymakers took no further action, Social Security could still pay three-fourths of scheduled benefits, relying on Social Security taxes as they are collected. Alarmists who claim that Social Security won’t be around when today’s young workers retire either misunderstand or misrepresent the projections. The long-term gap between Social Security’s projected income and promised benefits is estimated at 1 percent of gross domestic product (GDP) over the next 75 years (and 1.5 percent of GDP in the 75th year).
Policymakers should address Social Security’s long-term shortfall primarily by increasing Social Security’s tax revenues. Social Security will necessarily require an increasing share of our nation’s resources in the coming decades as the population ages, and polls show a widespread willingness to support it through higher tax contributions. Recent trends also justify boosting Social Security’s payroll tax revenue: Social Security’s tax base has eroded since the last time policymakers addressed solvency in 1983, largely due to increased inequality and the rising cost of non-taxed fringe benefits, such as health insurance.
