That was the intent when they created the program. SS was there IF you could live that long and could no longer work. As the vote buying process often goes with the left, it slowly became a retirement program and yet another government dependency.

During the administrations of Clinton, G.W. Bush, Obama, Trump, or Biden there were no significant legislation that raided or lowers benefits.
Fund shortfall in S.S. is due primary to the vast number of baby boomers becoming eligible for retirement, increases in early retirements, 10 years of low treasury bill interest, and increase life span of retirees. And yet the S.S. tax has remained 6.2% for 32 years.
There has been a over a dozen congressional commissions and ordered studies to save social security over the last 15 years. Of those exactly zero proposals have been implement. This is why I believe, there will be no bailout of social security and as the12 year milestone approaches and the 25% reduction in S.S benefits looms, congress will pass a law to pay the 25% for a couple years while they search for a solution and like the debt ceiling it will reauthorized over and over.
