Imagine that you have an appliance (say, a refrigerator) that you've had for awhile. It works well most of the time. But it costs more every year to maintain, and sometimes it doesn't work so well. The appliance is our health insurance/care system- mostly effective, but hugely expensive for the results we get (and of course, some people fall in the cracks and don't get the benefits).
The Libertarian position: who needs a refrigerator anyhow? (Read "insurance" for "refrigerator")
The Republican Establishment position: Our refrigerator is the best in the world. And if you disagree you're a socialist or a Nazi or something. (Or alternatively, see variations of Libertarian position above).
The Democratic position: We need a really expensive new refrigerator, we'll pay for it with a credit card that we don't plan to ever pay the balance on it, and we just hope that our grandchildren can afford to pay for it.
Somehow none of these positions really seem ideal.
