It appears so; you're looking back 100 years. I'm looking back in modern times (which I'd consider starting around World War 1).
> I also probably wouldn't aim a massively scoped wealth transfer program at enabling earlier retirement (admittedly you haven't stated a preference for this wealth transfer over other sorts of wealth transfer, you've just stated that it would make SS solvent).
62 is considered the earliest you can collect social security, with a steep reduction in benefits for the remainder of the collection period. 65 is standard. I don't consider 65 early retirement.
If you have a better idea than removing the SS tax cap, I'd love to hear it. Reducing benefits are not an option when existing benefits are barely keeping seniors out of poverty as it is.
