First off, SS wasn't designed with a "Trust Fund". It was essentially pay as you go.
Second, SS was given a "Trust Fund" in the 80's by St. Ronald of Reagan and Democrats who hate white people, because of the upcoming BabyBoomerArmageddon™.
That "Trust Fund" wasn't supposed to hold a balance for perpetuity.
So, the whole "SS is gonna go bankrupt" in 35 years isn't really accurate, as in, the "Trust Fund" is just extra money to cover the baby boomers.
Not to mention that SS has been 25 years from bankruptcy for the past 35 years...and will almost assuredly be 25 years from bankruptcy 5 years from now. And then another 5 years from then, etc, ad nauseam.
tl;dr: SS isn't an actual problem and the "Trust Fund" could be made permanent by simply removing the FICA cap. Period. End of story.
But, for the people who see that SS Trust Fund as an amazing opportunity to make themselves rich, they're going to go ahead and continue scaring people who don't know a god damn thing about SS into thinking it won't be there for them, so that people will stop caring about SS so that those people can then snatch up that money for themselves to make themselves rich.
