It doesn't even make sense--every day engineers and scientists make decisions trading off cost, effectiveness, and preventable death. The accountants and actuaries then sign off on it. It's not a deficiency of the professions, that's just how human society operates. Contrary to your assertion, we do not launch an investigation any time someone dies in a car accident. We don't start posting how the engineers at Ford are morally culpable for the death because if only they had used a more expensive XYZ widget our loved one would still be alive. Sometimes bad things happen and it's not anyone's fault.
