"It's not just countries that are getting richer -- individual people are, too. In 2005, the number of people worldwide living in absolute poverty, or on $1.25 or less a day, was around 1.3 billion, according to estimates from Laurence Chandy and Geoffrey Gertz of the Brookings Institution. The same researchers suggest it was below 900 million last year. From one-half of the developing world in 1981, they estimate the proportion of people in absolute poverty today at less than one-sixth."

This is an encouraging article on the state of the world, even taking in all the variables that make up the reality of the poor, there is an accepted theory that the poor are getting "richer".

So to everyone out there working against poverty and injustice...I say keep up the good work!
