Pension funds do it. Insurance companies do it. Canada does it, and so does Japan. So, why doesn't our Social Security system invest in the stock market--and should it?
I'm not talking about transforming Social Security into a system of private, individual IRA-style investment accounts, as proposed by former President George W. Bush and some conservative policy experts. The question here is whether Social Security should invest a portion of its reserve funds in equities to help the program's long-term solvency.
