True, but that said, rates in US hospitals are massively over-inflated. They get away with it, insurance companies are not pressuring enough to lower cost (they're probably in on it), and there is no real competition.
I don't disagree I just dislike the dishonesty being presented. The word free is used to make it seem much more palatable to put in universal healthcare and they know it. The reality is there are downsides to having universal healthcare.
