Some lady told me she read Atlas Shrugged while in the hospital for a long stay, kept alive by equipment she neither invented nor paid for. How oblivious people can be when we are all just barely something more than monkeys? Some of us manage to be passably unoblivious and I think that's what makes us human; the potential to be more rational than a monkey. It's no guarantee, though, as you so noted. You know there was a caveperson who just learned about fire and still went around and acted like he invented it straight up to the caveperson that did invent it. Monkey brain stuff.
