It seems to me from the UK that the word socialism is filthy dirty but the word communism is heavily and erroneously overused in the US. Those who want to prevent reform simply roll out the scary words and blackmail politicians and voters with them. There's nothing communist about the National Health Service, it's not even really seen here as socialist tho I suppose technically it is - most of the public seem to be pro a 'free at the point of access' healthcare system regardless of their voting preference.
our Labour (used to be socialist but now only barely left of centre) and Liberal-Democrats parties (= your Democrats) want to keep the NHS much as is, tho I suspect the Conservatives (=your Republicans) would privatise it given half a chance.
The NHS is actually the largest employer in Europe, the mind boggles as to what is spent on US healthcare, given that we in the UK spend much less that you in the US per head. Personally I feel it's a crying shame we can't all learn from one another, take the best of each other's systems. Although I know the US has huge problems with the results of poor lifestyle choices, there are also whole swathes that are totally on board with healthy eating, regular exercise and supplements, we don't seem to have that 'personal responsibility' to the same extent.
