The left criticizes Tea Party activists who oppose President Obama’s “socialism” as hypocritical because they do not oppose Social Security for themselves. The most common rebuttal is something along the lines of Social Security being fundamentally different because the recipients pay into it. This is no different than arguing for a right to steal your younger neighbor’s car because an older neighbor stole yours.

Most people are aware Social Security has begun paying out more in benefits than it collects in payroll taxes. However, it had run surpluses for decades that most beneficiaries honestly believe is funding the shortfall until the demographic imbalance caused by the baby boom evens out. Since they “paid into it all of their lives,” supporters of Social Security distinguish it from Aid to Dependent Children or other wealth transfer programs. Inherent in this thinking is both factual inaccuracy and flawed logic.

First, even if those surpluses had gone into a “trust fund,” no one disputes Social Security has always been a predominantly “pay-as-you-go” program. The overwhelming majority of the money collected from payroll taxes went to fund benefits for current beneficiaries. Thus, payroll taxes were taken from one group of people and paid out to another, just like public welfare.

One might argue the surpluses generated previously mean at least part of the money being paid to current beneficiaries is their own money, held in trust for their retirement. This is also completely untrue. The surpluses have not been held in cash since 1939. Instead, when the program runs a surplus, the government is legally obligated to use the money to purchase U.S. Treasury bonds, which are securities documenting you have loaned the federal government money. So, by law, any surplus collected in payroll taxes for Social Security must be lent to the federal government, which immediately spends it on operating expenses. In return, Treasury Bonds are put into the trust fund.

For those who decry this 1939 change as a betrayal, remember the FDR administration had also taken the U.S. off the gold standard (domestically). Had the government continued to merely hold reserves in cash, those reserves would have been outstripped by inflation by the time the benefits were payable to most beneficiaries.

Most people think of the treasury bond arrangement as the government putting their money into a “secure investment” which will pay them interest with very little risk. This is absurd. Treasury bonds are not “an investment.” An investment is a loan or advance of capital made in the hopes of earning interest from a producer of goods or services. The fundamental question anyone asks before risking their money with a bond issued by a private business is “How are you going to pay me back?”

The  private sector business answer would be, “By using the capital you have loaned us, we are going to expand our productive capacity. With the new products we will produce and sell, we will be able to pay back your investment with interest and still make a profit.” Thus, if you purchase a bond issued by a computer manufacturer (i.e. lend it money), then the computer manufacturer repays you with interest from sales of the new computers it produced using the money borrowed from you.

But the federal government doesn’t produce computers. The federal government doesn’t produce anything. How does it answer the question, “How will you pay me back?” There is only one possible answer: “We will tax people in the future to pay back your loan principle and interest.”

Thus, even the so-called “trust fund” does not represent a store of your own money, held in trust for your retirement. 100% of your money was spent the moment the government received it. Most went to underwrite current beneficiaries’ benefits. The rest was spent on other government boondoggles and replaced by promises to repay you by taxing other people. Not one dime of current benefits represents a “payback” of one’s own money. Social Security is every bit as “socialist” as Aid to Dependent Children, Medicaid, Medicare, or any other government transfer of wealth. Where do you think it got its name?

There is a bit of irony here that probably also escapes most Americans. While the federal government’s modus operandi for many years now has been to merely pay off the interest on its debt and issue new debt to cover the principal as bonds come due, let’s consider what would happen if they actually started repaying the principal on their bonds.

The longest term bond is a 30-year Treasury note, which means you loan the government the money for 30 years. Suppose that in 1970, you were a 34-year-old, dutifully paying your Social Security taxes. Most of your money went to pay current beneficiaries, but a small portion (your share of the surplus) went into 30-year Treasury notes. In 2010, you are one year from retirement and ask the government, “Where are you going to get the money to pay back the principal and interest on that 30-year Treasury bond?” As bizarre as the answer might seem, the answer would be, “Why, from you, of course.”

However, the most socialist aspect of Social Security is not that it represents a transfer of wealth. It is that the program is mandatory. The only way for the government to accomplish a transfer of wealth from one party to another is to force people to participate. This is why George W. Bush’s proposal to “privatize” Social Security would not have made it any less “socialist.” People would still have been forced to participate; only they would now have the option of handing their money over to W’s tax-subsidized buddies on Wall Street rather than to the federal government. Imagine if he had been successful in implementing this in 2004.

Free market capitalism and socialism truly are opposites, but the fundamental difference is one of rights, not economics. True free market capitalism recognizes every individual’s right to keep the product of his labor and dispose of it as he sees fit. Social Security denies this right. It should be responsibly phased out and replaced with nothing. That prospect should scare no one at this point. With a government $14 trillion in debt and planning to borrow more every year for the foreseeable future, I would trust the most irresponsible individual I know before the federal government – with his retirement money and mine.
