And yet with all that money you can’t buy European quality of life in the USA
EDIT: Also, a large part of "quality of life" has more to do with the structure of european country populations. They are old , cohesive and mostly conformist societies that tend to help each other in times of need, something that the US, which is individualistic country made of immigrants can never do. This creates a more safe environment to live, but it is not an excuse for lackluster economic performance.
