I hear you, that all makes sense, and I've been hearing it my entire life. When I was young, Social Security was supposed to end before the 21st Century, and yet, here we are.
I believe they've just been softening us up to accept it when they finally figure out some mechanism to kill it, and they can say "Well, we always said it couldn't last," and we'll say, "Yeah, it was good while it lasted."
Valid concepts. I like to speculate on the future Utopian Socialist America, too, if we can make it happen.
