>the rest of the developed world has universal coverage and healthcare

Why should every country have the same solution to healthcare? The US was formed as a democracy when 'the rest of the world' was run by monarchs. Healthcare is still a rivalrous good, and if we don't limit it by who can afford it, we will limit by some other ambiguous term like 'need.' My friend's grandma (80 yrs old) just had to fly to the US from Paris to have a surgery for which the French system deemed her ineligible (she was too old).
