Actually, funny thing. The other month or so I sat down at my favorite Mexican Restaurant in Santa Monica and overheard a group of doctors sitting behind me chatting about the health care reform. Being that Santa Monica is largely, and almost exclusively, Democrat they spoke in hushed tones, but luckily I had my back inches from the doctor doing most of the talking. He had something to do with the show The Doctors, but I could not determine exactly what. He didn't look like one of the on-air doctors.

The table's consensus was they didn't agree with government involvement. They also disliked the current system and thought insurance companies were a racket. My brother works in insurance, and he basically says the same thing about health insurance being a complete racket.

The doctors believed under the new system they'd see a lot of medical professionals and doctors leave the industry. They explained why they thought so in greater detail, but after about three or four of those damn margaritas I couldn't remember any specifics. Maybe this article touches on some of their concerns? I dunno.
