Hmm... seems like if you move a large number of people out of "extreme poverty" which was originally defined by the UN, and set at $1.90 a day by the World Bank, they're still going to end up under the "poverty line" of $5.00 a day as defined by your article. So I'm not sure how this constitutes a "trick". You'd have to move those people directly out of extreme poverty over the $5.00 a day in your article in order to drop the number of people in poverty. It's still frankly an improvement to move such a large number of people up the poverty scale. I'm sure i'd rather be living on $4 a day rather than $2.
