Health care in USA/vs UK or Canada?

Born in the UK & have lived in Canada 60 yrs. Many friends in the USA. I am elderly and have really great health care. I worked & paid into the system, of course. Hospitalized on many occasions, I have no fears. My friends in the USA have lots of fears and I can't help them. Can you? Presidents have been trying for years & years to fix this but why are they being stopped? I watch CNN and have heard the arguments from Insurance Companies and the Dispensers of Medication.........most of which are vitamins that are over the counter anyway. I need medication that is not over the counter and the cost is high. No cost to me because in Canada it is covered. This is Canada and this is not Socialism. (Mind you I think for the seriously ill to get the medication required they wouldn't care a whit if you called it Socialism to keep them out of pain without bankrupting an entire family). I do not believe religious beliefs have any place in relief of pain.
