Government-run healthcare isn't a panacea that will 'value human life' any more than the insurance companies. You are still a number in a database somewhere.
Most new drugs come out of the US and socialized governments create generics at a fraction of the cost, because they don't have to put any money into R&D.
The US is the back-bone of the medical system for the rest of the world and also has the best medical schools and best quality hospitals (the majority of people with money come to the US for life-saving surgeries..this has to tell you something).
We need to push the true costs of things to the patient, which will force the price down...not replace the existing inefficient layer of the insurance companies with an even more inefficient layer called the government.
This has worked with many cosmetic surgeries, which used to be very expensive, but aren't covered by insurance.
Insurance should only cover rare surgeries that can't use the free market to reduce the costs.
I can't think of anything that the government runs better than the private sector. Healthcare is no different.
