Glis, Social Security was never meant to be the sole income for retirees. It was supposed to be a safety net to be used in conjunction with one's own savings. Somewhee down that road, it morphed into what far too many people count on as their sole means of survival. If it hadn't been raided by President Johnson to fund the Vietnam War, or if the money taken for that purpose had been returned to the Soc. Sec. trust and not put into the general treasury, there would be much less chance of the fund going bust.
As a 71-year old who began to collect when I turned 70 while still employed full-time, I do believe that there have to be some changes made. For instance, now that the life expectancy for both men and women is 80+, there should be no early retirement at 62 unless a person is unemployable or chronically ill. I waited until I was 70 before collecting so that I could maximize the amount I would receive since it would be a fixed amount.
Another change would be to allow younger people who are starting out to put their money in an investment of their choice. However, knowing that Americans save less than any other Western country, I fear that if it was voluntary, very few would save for retirement. If that were to happen, how would they live at retirement age? They would become wards of the state and taxpayers would be footing an even higher welfare tab. Perhaps some measure of voluntary and involuntary savings could be achieved.
