My host family father is a doctor in the US. He said to me once something like, "Be prepared to be scammed by people whether it is a brain surgeon or a carpenter. Never ever trust the original price they quote on you and be critical of their output."
Have you seen how pharma reps treat doctors? I have. Hundreds of dollars worth of dinners/lunches (one of the dinners my gf and I were invited to, it served unlimited Wagyu beef for bbq; of course, we had to sign in before the dinner). I am disgusted by how cozy the relationship between pharma companies and docs are.
The more I talk to and observe doctors, pharma and healthcare industry in general, the more I lose respect to the parties involved (of course, there are a few respectable professionals, but they are a minority because of the sheer amount of money to be made in that industry).
