Why would anyone feel universal medical would have a negative effect when every single country that has universal medical started out with a system similar to the current "pay or suffer" system and have never switched back?
Not one country. English, French, Italians, Germans, Australians, Canadians....the list goes on and on. If a universal plan, any universal plan, had a negative effect surely one country would have switched back.
While politicians in every country with a universal plan gripe about it not one politician has seriously campaigned on dismantling such a plan.
It's difficult to comprehend why anyone would be opposed to a universal plan when the evidence shows every country which initiated one has kept it.
