@Sheril I think they look at it like dying of an infectious disease or winning the lottery -- that it most likely won't ever happen to them. Until it causes substantial inconvenience, injury, or financial losses to individuals, they can't be bothered. And even when it does affect them, they think it's a one-off and won't ever happen to them again. Humanity isn't good at understanding statistics and probabilities, and isn't empathetic enough to care about anything or anyone outside their own small circle.
