This anecdote may be true, but Sweden has significantly more favorable health outcomes across most dimensions compared to the US. Infant mortality, in-hospital mortality, etc.

In fact, most developed nations do. But part of what makes it so difficult to have a productive conversation about healthcare is that everyone has experience with the system in every single country, and bad experiences get passed around. So we say X country is doing better, and someone chimes in explaining how that country has its flaws.

They all have their flaws. But the US health system is measurably worse than most other developed nations across most axes that we care about. Though there are interesting questions about how much worse per-capita healthcare spend actually is given the comparatively higher R&D investment in the US.
