The July 22, 2007, twentieth anniversary of the Stewart B. McKinney Homeless Assistance Act calls for reflection on the persistence of mass homelessness in the United States, for consideration of what is needed to overcome homelessness, and for a new spirit of commitment and determination to eradicate this social evil.
