You're an idiot. The Social Security funds are invested in order to draw interest and grow in value.
OMG! Who told you that? … never mind… it was a rhetorical question. You people are dumb yesmen. Believing every shit they tell you and then spewing it back out as your own thoughts.
Starting WWII they dipped into it for the first time to support war spending. Since then it has been spent on every kind of shit resulting in the struggle to keep it afloat.
You are surely projecting your own idiocy.
Then go argue with the SSA, fucktard:
By law, income to the trust funds must be invested, on a daily basis, in securities guaranteed as to both principal and interest by the Federal government. All securities held by the trust funds are "special issues" of the United States Treasury. Such securities are available only to the trust funds.
In the past, the trust funds have held marketable Treasury securities, which are available to the general public. Unlike marketable securities, special issues can be redeemed at any time at face value. Marketable securities are subject to the forces of the open market and may suffer a loss, or enjoy a gain, if sold before maturity. Investment in special issues gives the trust funds the same flexibility as holding cash.

"The answer is that the federal government has borrowed all of that trust fund money and spent it, exactly as Krauthammer asserted. And the only way the trust fund can get some cash to pay Social Security benefits is if the federal government draws it from general revenues or borrows the money—which, of course, it can’t do because of the debt ceiling."
