In my experience, everyone in every profession thinks they do a great job and resents "external" comment or interference. In my experience, every profession fails, at times, to meet its own high standards. In my experience self-regulation doesn't work and, left to their own devices, professions fail to address shortcomings. With these points in mind, I welcome Mr. Calder's article. The venom and bile poured out on this board is just a dangerous symptom of an arrogant profession, which sees no need to justify itself to its customers.
