Good point.
One would like to think that the nefarious "science" of eugenics died out over 60 years ago, with the defeat of Nazi Germany. But when serious (?) people advocate our allocating scarce medical resources on the basis of age, physical condition (i.e. the presence or absence of chronic diseases), and mental condition, it would seem that the Dr. Mengeles of the world are still among us.
Have you read about the principals of triage in a disaster?
Scarce medical resources in a disaster are allocated according to who can survive.
As for me, if a pandemic occurred and there were scarce resources, I think they ought to be used on the young. It makes sense.
