Here's a quote from a senator in 1989, a warning from another respected senator in 1990, and one from the Clinton administration's 2000 budget worth considering in today's push to "trim" Social Security.
On October 13, 1989, Senator Ernest Hollings of SC stood on the Senate floor and warned, “…the most reprehensible fraud in this great jambalaya of frauds is the systematic and total ransacking of the Social Security trust fund…in the next century…the American people will wake up to the reality that those IOUs in the trust fund vault are a 21st century version of Confederate bank notes.”
In 1990, Senator Daniel Patrick Moynihan of New York, a member of the Greenspan Commission, and one of the strongest advocates the the 1983 legislation, became outraged when he learned that first Reagan, and then President George H.W. Bush used the surplus Social Security revenue to pay for other government programs instead of saving and investing it for the baby boomers. Moynihan locked horns with President Bush and proposed repealing the 1983 payroll tax hike. Moynihan’s view was that if the government could not keep its hands out of the Social Security cookie jar, the cookie jar should be emptied, so there would be no surplus Social Security revenue for the government to loot. President Bush would have no part of repealing the payroll tax hike. The “read-my-lips-no-new-taxes” president was not about to give up his huge slush fund.
A lot of people speak of those IOUs as if they can be pulled out and exchanged for money to pay benefit checks. They can’t. As the Clinton administration budget of 2000 explained, the securities in the Trust Fund ‘do not consist of real economic assets that can be drawn down in the future to fund benefits. Those special-issue bonds can only be redeemed by raising taxes, cutting spending elsewhere, or borrowing — exactly what the government would have to do if the Trust Fund didn’t exist. The Trust Fund, said the Clinton budget message, ‘does not, by itself, have any impact on the Government’s ability to pay benefits.
