Hmm, true. But we do have to remember that they're living in a world completely different from our own, one that is scientifically and socially implausible and maybe impossible, and fictional as it stands. We can't use that situation as a method of direct comparison, because it's unrealistic. The truth is, people just don't work that way they would have to be conditioned into that kind of thinking, which they are in the novel. But in this world, it'll never happen.
