The drivers of poor US life expectancy is mostly guns and cars. Cars are the #1 killer of Americans between 5 and 45 (approximately). That doesn’t have much to do with the medical system.
You missed the point. Cancer and heart disease primary kill people when they're already old. Treatment of those diseases, while important and necessary, doesn't impact average life expectancy much either way. Whereas fentanyl overdoses are now the leading cause of death for adults 18 - 45. That has a huge impact on average life expectancy because those people would have otherwise lived many more years.
Your information is outdated. The rate of accidental death among younger adults due to opioid poisonings has increased significantly in just the last few years.
My primary assertion was that life expectancy does not inform you about the quality of the US medical system. I focused on guns and cars, but adding opioids (and even lifestyle issues like obesity) doesn’t change my argument or the conclusion.
Someone dying a few years earlier than otherwise has a smaller impact on _life expectancy_ than someone dying young. Furthermore, the #1 cause is correlated with lifestyle factors which medical treatment has little control over.
