Less directly, there's the fact that new safety features often come to luxury vehicles first, and might eventually trickle down to cheaper cars due to competition and regulation (backup cameras, automatic emergency braking).
I think mostly we don't like to think about it. This comes up particularly in the health care industry. There was the (manufactured) furor over "death panels" but there's also the very real challenge of deciding whether it's worth paying possibly millions of dollars on a drug that might have a marginal-at-best improvement in someone's survival odds. And it's not just about some corporate executive's pockets; these costs get passed on to regular people through increased premiums and may cause people to drop their health insurance entirely.
