Dubai seems like the peak of inequality and ostentatious luxury even to those of us who don't live in America (I assume you mean "the US", not the Americas).

There are genuinely bad places in the world even factoring out "American exceptionalism/egocentrism". Dubai seems to be one of them.

I don't think that the author is American. Their X profile [1] seems to indicate that they are British.
