Several years ago, I was traveling back and forth to Italy, for a machine tool purchase and training. 5 Italian guys came over with the machine to do installation, and checkout, so I asked them about their socialized medicine. They said for general things, it was pretty good, and if you needed a heart transplant, they would give you one but chances were that one would die before the procedure could take place because of the wait times.So anecdotes don't work, and that's fair, but look up the instances of treatable cancer deaths in the UK.... documented long MRI and long breast scan wait times in Canada.
The wealthy in Italy go to private doctors and hospitals where they have to pay to get better health care. That's only one country, I have zero idea how the others operate that are supposed to be better than ours.
