When I was in high school in the early-mid Seventies, one of our Econ teachers made quite a stink by saying, "Social Security will be gone before you even get there."
He got some blowback from parents, as I recall. Boiled down, his argument was, "You're 15 now. You're on the tail end of the biggest population boom in the history of the nation. Sometime in the next 50 years there will be a recession or depression, and by the time you get to 65, it'll be gone. So if you want to retire, you're gonna have to do it your own damn self. Get a job with a good pension, because Social Security will be gone. Oh, by the way, it'll also help if your parents leave you a load of money."
