Essentially nobody is complaining about the quality of care available here. The problem is that only the rich can really afford it. Most people will avoid going to the doctor if at all possible, just because they can’t absorb the cost even if they’re just told to take an Aspirin and sleep it off. Long-term care for anything serious is just impossible to recover from financially for most people - it literally bankrupts entire families. With how hard it is to move up a prosperity bracket, that’s a devastating blow that is often felt for generations.
I think your view might be slightly skewed because you have free care available, and can go to the US or Mexico for better options if you can afford it. Here, if we can’t afford it, we have nothing, or we assume tens or hundreds of thousands of dollars in debt.
The way they describe it makes it sound like a story beat from a Black Mirror episode.
