Similar to how the UAW pension was stuff full of unsecured bonds from GM, and they went crying to the government for a handout after decades of idiot-level decision making.
Social Security has never been used as the general welfare fund, and it has better budget balance when there wasn't a large demographic bulge in retirement age.
Because, duh.
There are exactly 3 ways to get Social Security: retirement, survivorship, and disability. The first two were part of the original implementation, the last was added in 1956. Whether or not you consider adding disability benefits (which have a separate trust fund) to have transformed SS into a “general welfare” fund, the addition of retirement benefits doesn’t correlate with SS’s troubles, but Boomers reaching advanced age does. The Disability Insurance trust fund is actually projected to be solvent for 31 years longer than the Old Age and Survivors Insurance Trust Fund (2065 vs. 2034), so it's weird to blame it for the problems.
It makes zero sense. Eliminate that one thing and it would be the single largest tax increase in history. That tells me that people making $150k/year or more can live without being social security tax free every year after earning X amount
