> Poverty levels
Poverty levels are measured relative to median. Poverty in US and poverty in Bangladesh, Russia or Vietnam are completely different things.
In the US poverty line is about $16k, while in Russia for example it is $2300. Even considering the PPP it's like 4 times the difference in living standards. I guess Vietnam or Bangladesh are far worse.
