Some years ago I took on an assignment in a southern county to work with people on public welfare. What I wanted to do was show that everybody has the capacity to be self-sufficient and all we have to do is to activate them. I asked the county to pick a group of people who were on public welfare, people from different racial groups and different family constellations. I would then see them as a group for three hours every Friday.
