The intelligent, experienced ones who might be are not hired.
Your sister is a woman of deep insight. There are sometimes some bright lights passing through on their way to something better-medical and nursing students working their way through school-but the lifers tend to be either less smart or smart enough to keep a low profile. Often this takes the form of working nights and weekends, when there aren't very many suits around. I try to follow my old man's advice-"it's useful to be smarter than you look; the easiest way to accomplish that is to look a little dumber than you are."
Maybe we need another Forum: "Surviving in the health care system" or "Around the gurney". This is more likely to be a challenge for most of us than is survival in the boreal forest.
