The Social Security "trust fund" is an accounting myth.  It's just some special  US Treasury notes they keep in one drawer of a file cabinet in West Virginia.  According to the myth, they will only be able to pay 97% of what is owed to current beneficiaries in about ten years.  Does that mean they will stop paying anything to everyone?  No, it means that they will have to figure out a way, either to reduce everyone's benefits by 3%, or to raise taxes so that they can stay at 100%.  Neither of those solutions are popular, so the decision has been made to put off making a decision.
