One of the most interesting things about health politics and policy is that those mostly responsible for driving health costs — physicians — are the least concentrated interest group. If we want to know what the research-based pharmaceutical industry, the generic drug industry, the health insurers, the hospitals, or the medical-device makers want, we know where to go to find a fairly unified answer.
Physicians have no unified voice. The closest thing to a professional association for all physicians should be the American Medical Association, but it is not. It is a business that profits from a government-sanctioned monopoly on billing codes.
