The difficulty here is making health care a profitable business, which is at odds with providing good health care. American health care, even for the wealthy, is a miserable affair when someone really needs major care (such as following a traumatic accident). The patient becomes a liability for the insurance company and a profit center for the hospital, all of which is more important than the patient's long term recovery. That is not the only way American health care fails.

I would definitely welcome a unitified health care system in California.
