Just a note: Most often, it is not the doctors' salaries or time that is the major contributor to the cost of surgery. Instead, the ridiculous fees are created by the hospital administrators as a result of a long history of negotiations between insurance providers and hospital admins. Simple parts that cost $0.10 to manufacture will be billed at $20, rooms will be billed at $8000/night, etc.

To my knowledge, most doctors are trying to actively reduce healthcare costs on the end user. They don't see much of the profit, that just lines the coffers of the billion dollar for profit hospitals out there.
