Out of those three examples you gave, Western Europe still wins on 2/3 (higher life expectancy, higher quality of life). Granted the second is subjective somewhat, but I believe most would agree. The first is objectively lower in the US compared to Western Europe, you can check the statistics. Per capita GDP is only high in the US due to massive wealth inequality and a ridiculous concentration of billionaires. It's not "ignoring every contrary indicator", it's that most of the indicators that are used to support the idea that the US is "better" (e.g. per capita GDP) are fundamentally flawed in different ways, and don't amount to a proper comparison of the quality of life.
