According to the site it is.

Revenues -> Eliminate Tax Max without Benefit Credit (parent's #2) closes the gap by 68%.

Benefit Formula -> Slow Benefit Growth for Top Half of Earners (closest option to parent's #3) closes the gap by 41%.

Together these keep the program solvent indefinitely.

? the OP proposed raising the contribution limit & also hinted at some means testing "and you can't afford to live" -- which combined would absolutely be enough to close the gap depending on how aggressive you are with these changes.

I would let government decide “you cant afford to live” as much as I would let OJ Simpson date my daughter. but that would be a hoot as two parties controlling the government change. while one is in power, 99.99% of retirees would qualify, the other - 0.000065% :)

vacuous anti-government take that doesn’t really do anything to contribute to the discussion, imo. essentially “keep the government out of my social security!”

you have a comment to say what you don’t disagree with or just shooting the breeze?
