Naturally answers are proposed which do not address the heart of the matter. The basic problem is that most pay for routine health care services through a 3rd party payer. Most use a 3rd party payer as it is part of their or a family member's compensation or it is a government program. It's a standard workplace benefit owing to its exclusion from the income tax. When you pay a fraction of the cost of those routine services, then you are less likely to shop around and you are less likely to balk at additional, perhaps generally unnecessary services.
Greater government intervention in health care services is debated under the assumption that the government currently is not greatly involved. It is precisely its history of involvement which has led us to the mess we are in. Now we can understand that and move towards a solution based on that understanding, and recognize that any kind of reform should be based on the reality that the provision of health care services is a service, and as such is subject to all of the basic laws of economics which apply to every other good and service produced by a private party, or we can pretend that it is something else, and come up with an even greater monstrosity of stupidity, and continue to address everything but the root cause.
Of course, these debates are usually nonproductive. If someone believes the Earth was formed 5,000 years ago, in spite of all evidence to the contrary, because their faith tells them so, then it's generally not worth spending the time discussing matters of science and history with them. Such it usually is with those who advocate greater state involvement in our lives. It's not politics to them, it's religion, and they should be regarded as the ignorant fundamentalists they are.
