Because of government controls and bureaucratic incentives: on the one hand, the FDA is by its nature and rules inclined to block new drugs and medical devices; on the other hand, potential inventors are either turned off or handicapped by the FDA rules and controls. I've developed internal software tools for healthcare companies -- having had to study and learn the FDA rules, and having seen what these companies go through, I'd rather give up on engineering than work in the development of medical devices. A sane, creative mind cannot work and flourish under compulsion.
