> life expectancy is lower in the US than in most of western Europe

Could be more tied to poor diet and lifestyle, and not the healthcare system itself.

Like if you sit on the chair all day on your remote job, then move to the couch for after-work Netflix and PS5, while you drink soda and eat processed food, then the only time you leave your house is you drive your Tesla/F-150 to Walmart and McDonald's, there's no magic healthcare system in the world that can undo decades of self inflicted damage.

Meanwhile people in some impoverished balkan town could end up living longer because they spend their entire lives moving outdoor all day in fresh air and only eat organic what they grow on their plot of land, even if their hospitals and healthcare systems are significantly worse than what americans have.

There's way more variables to life expectancy than just the healthcare system.
