Piles of rice of greatly varying sizes represented groups of people throughout the world, one grain for each person. The rice pile for refugees was almost exactly the same size as the pile for millionaires. Imagine if each millionaire funded one refugee (not much money per person). The biggest pile in the whole room was people living with HIV/Aids in sub-Saharan Africa.
