Once upon a time, a discipline called "medical ethics" existed and was held in high regard. Medical ethics addressed the subjects of triage and best use of sparse resources in medicine: who to save when you cannot save everyone? New advances in medicine were welcomed and enthusiastically funded, because new and better medical technology meant improvements in health, lifespan and the ability to save more lives.
Somewhere along the way, overstressed, under funded medical ethics - a discipline whose members welcomed new medicines, new therapies and better ways to treat disease - became fat, well-funded "bioethics." Bioethics is concerned with slowing down the advance of medical science with deep philosophical and ethical questions that can only be answered by means of large salaries, hundred million dollar buildings, and political interventions.
In short, medical ethics lost its way and become corrupted by power.
