There was a recent HN post about a weight-loss drug where I bit my tongue and did not try to "rebut" stuff there with a comment about diet and lifestyle . Methinks this problem runs deeper than paying doctors to promote drugs. Americans fundamentally seem to see drugs and surgeries as "health care" in a way I find concerning.
I once overheard a coworker give a doctor a right bollocking over the phone because he wouldn't prescribe antibiotics for her daughter who had the flu, and she then proceeded to tell rant how ridiculous that doctor was. I've rarely had to spend more effort to stop myself from saying some rather unpleasant (albeit true) things.
