True, but how much choice do you have with health care? If you belong to an HMO, you just can't pick any doctor you want, if you get health insurance from your employer then you just can't pick any insurance company to deal with.
In any case all the insurance companies belong to a central data base which tracks your underwriting and claims.
I suppose you could pay for everything yourself, but that is a quick way to bankruptcy unless you are exceedingly wealthy.
Well, you can choose not to take an HMO but a PPO instead, you can do what so many of the Undocumented's do by us, use the Hospital's ED as your PCP, poor it up and go to a Doc in the Box, or work the system. There are ways to choose your health care.
As far as the Databases, I don't deny they exist, but access to them is Limited by HIPPA... For example, I work at the hospital, and I cannot just access a medical record... every time I do it flags the record, and I need to be prepared if the JC comes in and does auditing (which they did last week) I need to explain why I was in those records. I ask you who will really be providing that kind of oversight to the Government or their "National Coordinator of Health Information Technology"... I guessing no one really.
