I think that's just it: trying to promote better cross cultural understanding. That's something I tried with the GP here, but I could probably write up an article to be linked to in such discussions.
> metrics like "How many meals per day do you get?" and "What kind of shelter do you have?"
I think this is a good thought, a focus on qualitative differences in lived experience using quantifiable metrics. With that approach you're less likely to offend rather than inform. Might be best to skip the "less than 1/2 of one percent of Americans were poor by standards in India" since it seems to suggest that American poverty isn't "real" poverty.
I would even go so far as to say that communicating the cultural context is far more important than underlining the economics, the former of which TFA is attempting to do.
