Cui bono?

I don't know if anyone else heard this NPR story, but I found it rather wrong-headed.

What is the public option? So far as I can tell, it's a government-run insurance program that will, through competition with private plans, provide a minimum level of insurance to all comers.

Frankly put, do doctors care where their money comes from? If they are rational actors, the answer is no. As long as someone else is paying the bill (and not looking at it), why should they? So why should we care about the opinions of physicians on whether or not health insurance companies need competition?

My fundamental theory about the 2009 version of health care reform is "who's taking one for the team?" Here's my list, in order of likelihood: insurers, pharmaceutical companies and actual health care providers. Anyone disagree?
