“... only 75% of the stated benefits that I have earned will be available in 2025 as a result of unfunded liabilities.”
I haven’t seen the Statement that you are talking about, but I suspect that what it means is that the missing 25%, which was an excess paid over the last twenty years or so, has not been saved as a fund to cover the baby boomer’s coming shortfall (as was the plan devised under Alan Greenspans’s supervision in the 80’s), but has been spent to cover past excesses of our government. In this sense, the Statement is correct. However, if you take into consideration the total amount paid in, I think you will find that it balances with the amount paid out for another twenty years. The problem was not social security itself, but the government’s overspending in general.
Apparently the statement is not on all potential beneficiary's statements. It's been on mine for several years. I have a .pdf (redacted) copy I made on the home computer.
I agree with the rest of your statement explaining why the SS department is notifying me of my future 25% reduction in benefits. :o)
I have VERY low expectations of social security in my future. Anything I get will be bonus if I retire before I die.
