"Imagine a large river with a high waterfall. At the bottom of this waterfall hundreds of people are working frantically trying to save those who have fallen into the river and have fallen down the waterfall, many of them drowning. As the people along the shore are trying to rescue as many as possible one individual looks up and sees a seemingly never-ending stream of people falling down the waterfall and begins to run upstream. One of other rescuers hollers, "Where are you going? There are so many people that need help here." To which the man replied, "I'm going upstream to find out why so many people are falling into the river." - Saul Alinsky, in Shelden & Maccallair
