A significant number of animals we own are livestock, and a significant number of those are given antibiotics to bulk up, rather than to help them get better. How is this benefitting the “patient” recieving the medication? Seems that treatment is purely for the owner. If we were to talk about pets, I’d submit that a pet would not choose to get neutered, or have their ears or tails docked. Again, purely for the benefit of the owner.
To me it seems an apt comparison, given the enormous amounts of antidepressents given to humans, to mitigate the same kinds of issues of overcrowding and negligence.
And looking at cancer treatment through the filter of productivity, makes me wonder who is supposed to be benefitting from such treatment.
