Agree 100%. There are kinds of costs farmers have which are new. The one I see is the inability to treats minor infections. Older antibiotics used to be OTC now they require a vet. Large animal vets are few and far between in many areas.
You ought to see enrollment at vet schools. Here something like 80% are female and they don’t do large animals. In fact, they don’t do small ones either for very long as they go to raising children.
We used to do a whole lot or most of treatment ourselves but now a lot of things are not OTC as you say.
