n January 31, 1940, Miss Ida Fuller received a check for $22.54. She was the first person to retire under the Old-Age, Survivors, and Disability Insurance (OASDI) scheme, better known as Social Security. At the time of her retirement in 1939, she had paid just $22 in Social Security taxes. Ms. Fuller lived to be 100, cashing over $20,000 worth of Social Security checks.
How Social Security Is Funded
If she had only paid $22.54 in contributions, where did the $20,000 Ms. Fuller received in Social Security payouts come from? It came, as it does now, from the taxpayers of the day. As of 2019, your employer deducts 6.2 percent of your wages up to $132,900 a year, matches this amount, and sends it to the Social Security Administration (SSA). The SSA deposits this with the Treasury, which spends it and receives Treasury bonds in return. This is the fabled trust fund that guarantees Social Security.
But these Treasury bonds are simply IOUs redeemable against the income of tomorrow’s taxpayers. When one of the Treasury bonds held by the SSA falls due for payment, the Treasury can only get the funds to meet this liability by taxing, borrowing (taxing the taxpayers of tomorrow), or printing money (imposing an inflation tax). In each case, what really guarantees Social Security is not the money you paid in but the earnings of today’s or tomorrow’s taxpayers.
The Golden Age of Social Security
Such a pay-as-you-go scheme could chug along well enough as long as there were lots of workers relative to retirees. When the program began, every 100 workers were supporting three retirees.
This favorable ratio encouraged politicians to be more generous. Originally intended to cover only about 50 percent of all workers, Social Security was expanded even before Ida Fuller received her first check to provide benefits for dependents of retired workers and surviving dependents. In the post-war years, Social Security grew further. Disability benefits, payable as early as age 50, were added in 1956, and during the 1950s coverage was extended to other previously excluded workers, making it essentially universal. Congress passed across-the-board benefit increases of 7 percent (1965), 13 percent (1967), 15 percent (1969), 10 percent (1971), 20 percent (1972), and 11 percent (1974). In 1972, benefits were tied to the Consumer Price Index, yielding an annual “cost of living adjustment.”
In 1965, Medicare was signed into law, establishing a heavily subsidized federal health care program for the elderly. Former President Harry Truman and his wife received the first Medicare cards without paying a cent in Medicare taxes.
Like Social Security, Medicare is financed by a payroll tax of 2.9 percent split between employer and employee, up from 0.7 percent in 1966. Like Social Security, that money gets paid right out to meet current expenses, which were vastly expanded by passage of Medicare Part D in 2003. And like Social Security, such a pay-as-you-go scheme could chug along well enough as long as there were lots of workers relative to retirees.
Entitlements vs. Demographics
Two things derailed that. US birth rates fell from births 3.65 births per woman in 1965 to 1.80 in 2016, and life expectancy rose from 68 in 1950 to 79 today. Together, this meant ever more retirees relative to the workers supporting them. By 2017, 100 workers were supporting 25 retirees.
These shifting demographics have shredded the solvency of the “trust funds.” Social Security is estimated to run out of reserves in 2034, after which benefits would have to be reduced by about 25 percent to keep spending within available annual revenue. Over 75 years, Social Security has an unfunded liability of $13.9 trillion.
The Medicare hospital insurance trust fund will run out of reserves in 2026. Medicare’s second trust fund, for physician and outpatient services and for prescription drugs, is permanently “solvent” because it has an unlimited call on the general fund of the Treasury—the incomes of future taxpayers. Premiums paid by the beneficiaries will cover only about 25 percent of program costs; the rest of the spending is unfinanced. Medicare’s overall unfunded liability over 75 years is more than $37 trillion.
The Future Is Bleak
The taxes levied to fund Social Security have already risen drastically. In 1937, the Social Security tax rate was one percent on earnings up to $3,000 ($53,449 in 2019 dollars) to be matched by the employer. By 1971 it was 4.6 percent on earnings up to $7,800 ($49,411 in 2019 dollars). It now stands at 6.2 percent up to $132,900.
This is only going to get worse. According to Census Bureau projections, by 2030 each 100 working-age Americans will be supporting 35 retirees, and this could rise to 42 by 2060. Another way to think of this is to calculate the number of retirees each worker must support. In 1946, the burden of one retiree was shared between 42 workers. Today, according to the SSA, roughly three workers cover each retiree’s Social Security and Medicare benefits. By 2030, however, there will be only two workers supporting each retiree.
In other words, a working couple will have to support not only themselves and their family but also someone outside the family thanks to Social Security and Medicare.
To make Social Security solvent again, the payroll tax rate would need to be hiked immediately from 12.4 percent to 15.2 percent, or Social Security benefits would need to be cut on a permanent basis by about 17 percent. According to economists Roger LeRoy Miller, Daniel K. Benjamin, and Douglass C. North:
[F]or Social Security and Medicare to stay as they are, the payroll tax rate may have to rise to 25 percent of wages over the next decade. And a payroll tax rate of 40 percent is not unlikely by the middle of the twenty-first century.
