JUST WONDERING…

“The fight against poverty will not be won until the inequality crisis is tackled.” 
That sentence is from a “briefing paper” entitled “An Economy for the 1%: How Privilege and Power in the Economy Drive Extreme Inequality and How This Can be Stopped,”  published recently by an organization called Oxfam.  Later in the same paper, however, they say: “Oxfam is unequivocal in welcoming the fantastic progress that has helped to halve the number of people living below the extreme poverty line between 1990 and 2010.”
I have never heard of Oxfam before.  For all I know, they do good work.  But aren’t those two sentences a bit inconsistent?  If the “inequality crisis,” and therefore poverty, is worsening (the thesis of the paper), then how do they reconcile that with the fact that, as they say, the number of people living in extreme poverty has been cut in half?
