Freedman is quite the evangelist about the potential of older Americans to engage in transforming the world around them. He founded Civic Ventures for starters. He's also just published a new book, Encore: Finding Work That Matters in the Second Half of Life. In a statement about the Purpose Prize finalists, Freedman gave some context to this rise in 60+ social entrepreneurs:

As baby boomers leave their midlife careers and continue working into their 60s, we are experiencing the biggest transformation of the American workforce since the women's movement. One of the most interesting and significant developments from this transformation is the emergence of social innovation and entrepreneurialism from people over 60.
