I would add acouple salient points.
1) National tort reform has never been a priority of physician groups, with most specialty groups willing to emphasize legal experimentation on the state level.
2) Physicians tend to view health care as a value-added product which provides a more efficient work force. We need to deliver this product wihtin a workable, cost-effective "system".
The AMA has an excellent PDF of "frequently asked questions", and while this is designed to answer physicians' concerns I think it is useful for everyone to understand the perspective from which doctors are coming. Read it here.
