Its no doubt true what you say but I don't see the relevance. Why should healthcare conform to free market economy rules. Do we do that for education, defense, firefighters or police. No. We accept that these are different. Why should healthcare be treated differently from education or even defense. Health kills more people than wars. Health is more important than education.
Perhaps the point is how much importance people (Brits) attach to healthcare and the benefits to the nation and governments in giving the people what they want.
