If it were increased again by the future expected increase in life expectancy, say hypothetically five years, the fix still would provide benefits for the same 18 years of retirement that the system provides now on average, and the unfunded liability would fall, leaving our children and grandchildren with less debt. However, if it were the only fix, workers would suffer needlessly for at least two reasons.
First, an increase in the retirement age is simply a cut in benefits, which already are low relative to their cost. Second, it does not address why Social Security’s benefits are so low in the first place. They are so low because they are financed by taxing wages. Because benefits are linked to wages, which increase about 1.5 percent per year on average, benefits increase about the same. This is somewhat akin to saving and investing and receiving a real rate of return of 1.5 percent. Until we migrate to saving and investing in capital markets, whose long‐run returns are significantly higher than 1.5 percent, benefits always will be unnecessarily low and Social Security will never be fixed.
To compare one financing system to the other, consider an average‐wage worker who entered the labor force at age 20 in 1964, worked 45 years and retired at the end of 2008. His wage history provided him a first‐year Social Security benefit of $18,324. Under present law, his benefit will increase with inflation and will be paid until his death — about 13 years based on estimated life expectancy.
Now assume he invested the same amount he paid in taxes, employee and employer combined, in a diversified portfolio of stocks and bonds with a 70–30 balance for 35 years and then a conservative 50–50 balance for the remaining 10 years. He retired at the end of 2008, when he suffered a significant loss because stock markets around the globe collapsed, down 37 percent in the United States alone. Yet even after the loss, his accumulated wealth still would provide more than Social Security’s $18,324 benefit, namely $30,000 in the first year, and indexed for inflation for 19 more years. If he chose to withdraw just $18,324 initially, his portfolio would last 39 years. And this assumes that his portfolio during retirement earns just a 1.7 percent real rate of return.
If life expectancy increases five years and he works another five years, the portfolio provides $48,000 in the first year, again indexed for inflation for the next 19 years. Or if he withdraws the original Social Security benefit of $18,324, the portfolio would not be exhausted until his 134th birthday. In stark comparison, an average‐wage worker who is stuck in Social Security and works and pays taxes an additional five years would receive little more than the original $18,324 in his first year of retirement, and it is indexed thereafter.
Because Social Security’s benefits are so low relative to their costs, all workers suffer. Social Security is simply a bad deal. That is why it’s mandatory.
The president’s commission has the opportunity to propose fundamental reform along market‐based principles, including personal property rights. If instead it promotes raising the retirement age or cutting benefits by some other formula such as progressive price indexing and its proposal is enacted, American workers and America will suffer a high price. Hopefully, the commission’s recommendation will not further destroy the country from within.
