Jeannette Walls on Poverty and Homelessness

Jeannette Walls, author of the award winning memoir "The Glass Castle," talks to NOW about the need to help get homeless people off the streets and into housing and describes how the suffering she endured as a child helped her become a successful journalist. Walls believes the best way to help homeless people in America is to give them skills and education. "As far as I'm concerned the best public policies are the ones that help people help themselves," Walls tells NOW Senior Correspondent Maria Hinojosa.
