Part of me wants to accept this information, but I am worried that some kind of Freakonomics will come into play and we'll find that the reason why there appears to be less poor is because X is no longer being considered as Y.
I wonder - is the amount adjusted base on cost of living and inflation? IE if $2 a day now gets the poor the same as $1.50 in the 90s, they haven't really gained anything.
