After U.S. national debt exceeded $40 trillion this month, discussions about the sustainability of the social security system have heated up again. Foreign media commented that as the baby boomers enter retirement in large numbers, spending on social security and healthcare is accelerating the pressure on federal finances, and the burden on young workers under the current system is also increasing.
2032 or a critical juncture may be reached
The US Congressional Budget Office previously estimated that between 2023 and 2033, social security and healthcare would account for 81% of the increase in mandatory expenditures. In 2026 alone, the increase in spending on social security and healthcare accounted for nearly half of the new total in mandatory expenditures.
At the same time, debt interest payments are also on the rise. The Congressional Budget Office estimates that the net interest cost for the U.S. federal government will exceed one trillion dollars in 2026 and rise to 2.1 trillion dollars by 2036.
According to the 2026 Social Security Trustees Report of the United States, the Old Age and Survivors Insurance Trust Fund is expected to be depleted in the fourth quarter of 2032. If Congress does not take action by then, the ongoing income from various programs will only be able to cover 78% of the established retirement benefits. If calculated on a consolidated basis, the Social Security Trust Fund is expected to be depleted in 2034, with a payable ratio of about 83% at that time.
The current system relies on the contributions of working people.
The U.S. social security system adopts a "pay-as-you-go" model, where taxes collected in the current period are primarily used to fund the benefits of retirees in that same period. According to current rules, in 2026, employees and employers will each contribute 6.2% of their wages to social security taxes, with a taxable wage cap of $184,500; self-employed individuals will bear a total tax rate of 12.4%.
This structure operates more smoothly when the labor force is relatively abundant, but as the aging population accelerates, the pressure to maintain a balance between income and expenditure significantly increases. The article cites data stating that a worker who retires in 2027 at the median wage level is expected to receive about $730,000 in social security benefits over their lifetime, while the total contributions made by the worker and their employer amount to less than $200,000.
If only the direct contributions made by individuals are considered, the lifetime benefits amount to approximately 265% of their total cumulative contributions. Based on this, the article argues that the current system still relies to a large extent on today's workers to provide financial support for the retired population.
The quota scheme is aimed at high-income retirees.
A proposal put forward by the Responsible Federal Budget Committee of the United States is to set a welfare cap for retirees with the highest incomes. This proposal, known as the "six-figure cap," suggests setting an annual social security welfare cap of $100,000 for couples at the normal retirement age, and $50,000 for single retirees, with adjustments made according to marital status and age of receipt.
The article states that the impact of this scheme is very limited in its initial phase. The institution estimates that in the early stages, it will only affect about 0.05% of couples, mainly those with an annual retirement income exceeding $2.5 million and net assets exceeding $65 million. However, as the maximum benefits of social security continue to rise, the scope of impact of this restriction may gradually expand.
Wealth transfer is not evenly distributed.
The article also mentions that the baby boomers collectively hold about $93 trillion in wealth, but it is estimated that only about $36 trillion of this will be transferred to the millennials and Generation X over the next 20 years. The remaining portion will be consumed by taxes, debt, and retirement expenses, with wealth being more concentrated among high-net-worth families.
Comments suggest that the initial purpose of the U.S. social security system was to provide social insurance, rather than a welfare program based on income review. As a result, individuals with higher incomes throughout their careers can typically continue to receive higher benefits according to the established formula, even if this portion of their income does not constitute a large proportion of their total wealth. The article argues that policymakers should re-examine the goals of the system, placing more emphasis on protecting against poverty in old age, while also freeing up more savings space for younger workers.
