It sounds like the calculation of the 1% isn't relative, though of course the gap between 32k and the top number is astonishing.

I think you raise a good point, but I'm not sure how we should normalize our ideas of wealth in an equitable way internationally.

So, is it fair to compare someone in the US living of 32K a year and someone earning 32K a year where the laborers are being paid $2 a day, well the answer to that is yes. After all you would be talking about edge case, as there isn't a lot of people living in those circumstances in developing countries, while the mass in the US is living under those circumstances.

If you want to talk about the "standard" of living, then the cost of the same standard in developing countries is often the same as developed countries, Petrol, cars, healthcare (though this may differ in some areas), quality food, are comparative in cost, as many of these products are provided from the same or similar sources as where US consumers get their products.
