Finding doctors is a huge problem. When you move to a new city, you are given a list of 2000 PCPs and told to pick one (after calling around to see if they are accepting new patients). When you need to see a specialist, you are given a referral. People in the health care industry know that many of the specialists are untalented losers who push patients in and out as quickly as possible, and would never let someone close to them see them. The general public has little idea.
