Increase in the Dependency Ratio

If the Economic Report of the President figures are to be believed, the coming increase in the dependency ratio means that Social Security payments would have to decrease by about 45 percent if the Social Security budget were to be balanced every year. The reality is that this simply will not happen. First, the Social Security system does not simply calculate payouts on the basis of current Social Security receipts. In fact, there is a complicated formula whereby individuals receive a payout based on their average earnings over the 30 years during which they earned the most. [3] Of course, that formula could be changed, but it is unlikely that policymakers will completely abandon the principle that payments are based on past earnings. Second, retired persons already make up a formidable political lobby in the United States. As they become more numerous relative to the rest of the population, their political influence is likely to become even greater. Unless the political landscape changes massively, we can expect that the baby boom generation will have the political power to prevent a massive reduction in their Social Security payments. Social Security Imbalances To completely understand both the current situation and the future evolution of Social Security, we must make one last change in our analysis. Although the Social Security system was roughly in balance for the first half-century of its existence, that is no longer the case. Because payments are calculated on the basis of past earnings, it is possible for revenues to exceed outlays or be smaller than outlays. This means that the system is not operating on a strict pay-as-you-go basis. When the government originally established Social Security, it set up something called the Social Security Trust Fund—think of it as being like a big bank account. Current workers pay contributions into this account, and the account also makes payments to retired workers. Under a strict pay-as-you-go system, the balance in the trust fund would always be zero. In fact, in some years payments to workers are smaller than tax receipts, in which case the extra goes into the Trust Fund. In other year payments exceed receipts, and the difference is paid for out of the Trust Fund. To be more precise, tax revenues = number of workers × Social Security taxes = number of workers × tax rate × income and Social Security payments = number of retirees × Social Security payment. If tax revenues exceed payments, then the system is running a surplus: it is taking in more in income each period than it is paying out to retirees.
