My concern is that this sort of approach to medicine is going to result is the "top specialist" tier of doctors spending more time treating complaints that don't really require their particular level of expertise. You probably don't need to see the world's best cardiologist if you just have high blood pressure, but if you are paying 40k a year for a concierge medical service they might feel that the need to get you in front of him or her in order to justify their fee. Otherwise what are you paying for? Consequently this amazing heart doctor spends an hour telling you to eat better and exercise rather than evaluating someone's complicated and life threatening condition.
