Which list (there are many of them, made by different groups with different political positions)? How do you measure “sustainability development goal,” or living standards of a person? Who defines these terms, provides data, publishes these lists, why is it relevant amid countless other indices, Etc. You can always define an index that would put a given country or region at any position, or to advance a point.

You do better, living and experiencing life in different countries, or ask people who have done so. Not dismissing data, but there are a lot of stuff not captured by a number (not to mention the issue with data and the method used).

For example, there are other articles that claim poor people in US are richer than the middle class in much of the Europe (like a lower class or poor family in US might only have one car, rather than several, comparable to the middle or upper class in EU):

Regardless, the point in my comment remains.
