No, actually the reason you don't read in Health Affairs all about the stuff they fervently believe in is not because academia is ruled by ideologues, it's because what they believe is not true, and the purpose of academic inquiry is to find the truth. Excerpt:
The Duke group’s guest speakers included Dr. Keith Smith, an Oklahoma City anesthesiologist whose surgical center lists the costs of its medical procedures online in a move toward price transparency. The practice only accepts private health insurance, not Medicaid or Medicare. . . .
The Benjamin Rush Society traces its roots to 2008, when Canadian activist Sally Pipes organized a Washington meeting with support from the Kansas City-based Ewing Marion Kauffman Foundation. Its credo: “the profession of medicine calls its practitioners to serve their patients rather than the government.” Conversely, they also support so-called “concierge medicine” in which those with more money pay for individualized care otherwise unavailable.
Now, personally, I have no problem with that. They can refuse to take insurance and only work for rich people if they want to. However, it does not follow that the Free Market™ therefor is the solution to our dysfunctional health care system because think about it Randroids: what happens to people who cannot afford to pay Dr. Keith Smith for an appendectomy when there isn't any Medicaid or Medicare?
