Hmmm? I know/knew several older people who did not/do not use it. One of them, a retired school teacher of all things, has stated that he would rather die than use social security or medicare.He was POed all of his life that they were "stealing from my paycheck and I'll be damned if I will give them the satisfaction of doling it out to me now like they're doing me some kind of big favor!"
He had his military retirement, his teachers pension, and what he had saved/invested most of his life, and that's what he lived on, along with his own health insurance that he choose for himself and paid for with his own money. And he lived pretty good too, probably could have lived even better if he had all the money stolen from him by "the government" during his lifetime!
When he died he left his children a pretty substantial estate to divy up......and he left me a nice old shotgun.
He was one of the few men I admired and I'm glad I had him for a friend!
