Today social justice represents one of the most serious challenges to the conscience of the world. The abyss between those who are within the world 'order' and those who are excluded is widening day by day. The use of leading-edge technologies has made it possible to accumulate wealth in a way that is fantastic but perverse because it is unjustly distributed. Twenty-percent of humankind control eighty percent of all means of life. That fact creates a dangerous imbalance in the movement of history.
-- Leonardo Boff
