Can't you just look at life expectancy, and life expectancy in good health? Because the data I found doesn't put the US in the top anything. Even if you're in the top decile of earners.

How does that account for a population who..

..74% are overweight or obese

..less than 10% meet the fruit and vegetable recommendations

..25% get the recommended amount of exercise

..eat more than 70g added sugar a day

Healthcare really has the deck stacked against it however you look at it
