Privatization and profit based models are very efficient for many fields, but healthcare is a very different beast to control in this way. You may be singing a very different song if you were in different circumstances.
Do not apply blanket policies, which is what the insurance companies do in order to refuse some very basic and necessary stuff.
When you go to the best/top rated doctors (based on experience in field), the first question they ask you is HMO or PPO?? The insurances create so much trouble for these doctors when it comes to paying for some tests and visits, that many docs would think 10 times before ordering a test.
This is good in cost reduction, but it also strips a professional of decision making capacity. If the doc does the test, the insurance will bite them. If they dont do the test, the patient might come back with a tort law suit. Guess who is left holding the bag? The patient, who doesnt have the necessary education to analyse his situation. Is it any wonder that healthcare is in shambles?
