The world has become relatively less poor in the last few decades. People under conditions of extreme poverty -- that is, living on less than $1.25 per day -- have declined as a proportion of the world population, from 52 percent in 1981 to 22 percent in 2008.

Or are we better off with the private sector and nongovernmental organizations (NGOs) doing the job?
