The reason health care is socialized in civilized countries is not only to provide health care to citizens who otherwise could not afford it, but also to reduce the cost. In a privatized system, a profit has to be turned at every level: the general practitioner, the specialist, the diagnostic facility, the ambulance service, the emergency room, the hospital, the hospice, the health insurance company. All of these levels of profit build up the cost.
In the hybrid system with which the US is afflicted, regulation drives the cost even higher. It is not only government regulation because of Medicare and Medicaid, but also private regulation imposed by private insurance companies. In America, alone in the world, medical care comes second to paperwork.
Doctors working in medical clinics have to dictate the results of each patient seen, the diagnosis, the treatment, and so forth, in sufficient detail to satisfy the payer of the bill, whether public or private. The dictation time eats into the doctor's treatment time. In other words, the paper work requirements reduce the amount of time the doctor has to see patients. The paperwork also requires nurses to organize and compile it. And this is not the end of it.
