That's a favorite trick of politicians for criticizing health care proposals.
There are hundreds of different factors that you could use to compare the health care systems of any two countries.
When someone proposes some change, and offers country X as an example of a place that works that way, opponents can always find among those hundreds of factors some particular things where we have better care than X, and then that's all they talk about.
And of course if you propose a change and do NOT cite places that already work that way, then the opponents say you are trying something that is just theoretical and it would be irresponsible to risk our health on such experiments.
