Social Security privatization has been vigorously challenged on both economic and technical grounds. It has been said again and again that privatization increases risk for prospective retirees without solving the long-term Social Security financing shortfall (if there actually is one). It has been argued that privatization is merely a scheme to divert money from the Social Security trust fund for speculative stock market investments. And it has been noted that it creates new costs (portfolio management, government oversight) without being able to guarantee workers future retirement benefits.
Yet the most profound cost of privatization has been wholly ignored: the systemic cost to our public way of life. By turning a public social insurance and pension policy into a private bet in which personal and private decisions determine who does well and who does badly, we do irreparable harm to our democratic "common ground." After all, one of this nation's greatest public goods has been its promise to give every working family a guarantee of support at retirement, or in case of disability or death. This promise, offered to all citizens, wipes away all the distorting traces of class, race and gender that often play out so dismayingly in the private realm. You cannot simply take justice out of the public realm and put it into the private realm without fundamentally weakening the democracy on which the very possibility of justice depends.
Conservatives ought to recognize even more quickly than liberals that privatization -- whether of education, housing or Social Security -- makes us less of a public. It diminishes the republic -- the res publica, or public things that define our commonweal. It turns the common "we" into a collection of private "me's." It opts for market Darwinism, in which smart investors prosper but others lose, rather than social justice as its organizing principle. It demeans the "us" by turning "us" into "it" -- the big, bad, faceless government bureaucracy. And it privileges the private and individual by appealing to market liberty, as if people could really be free one by one or as consumers alone.
Private market liberty is not political liberty; it is only personal choice. It may generate private benefits ("I want an SUV!" or "Give me 100 shares of EBay!") but offers nothing for the common good (a fuel conservation policy, for instance). It is as citizens that we pay our Social Security taxes, and it should be as citizens that we enjoy the fruits of our labor.
