The US can't really be said to have a health care "system". What it has is a lack of a system, so there is nothing to dismantle. What the US has is a health care market, which is something else entirely. So what needs to be done is to build a health care system, as other countries have done. We're in a much better situation for doing that than they were when they built theirs, since we can learn a lot from the systems that are being used in other countries, and their successes and failures. We can also learn from the successes and failures of other countries about the best way to approach the question of how to define our community.

The only reason we don't currently have a universal health care system is as noted above, we are in bondage to huge corporate interests that only care about money and don't care how many people have to die in order for them to maximize their profits and enrich their shareholders.
