I read an interesting article a while back, which asked... why were so many of the doctors in Nazi Germany willing to engage in sterilizing mentally deficient people, and other atrocities?[1]

The answer was because, healthcare was viewed as a collective good. Doctors did not treat a patient for their own benefit, they treated a patient for society's benefit.

And I see echoes of that here.
