Innovation and government control in health care

Arnold Kling writes that government control over health care will reduce innovation because "government is much more likely to protect incumbents."

I agree. The most important potential medical innovations (especially among those that reduce costs) would destroy many doctors' jobs. For example, rather than paying Radiologists $500,000 a year it would be much better if someone could write a computer program that did the work of a radiologist. Similarly, the role of primary care doctors in diagnosing diseases and suggesting drugs could be eliminated by computer programs. But it seems unlikely that the government would ever help terminate the jobs of doctors given the tremendous political power of the medical profession and the high regard by which doctors are held by most Americans.
