Since Talbott wrote about the "shame of the cities," we have witnessed an epidemic of homelessness, with increasing numbers of women and children on the streets. Although the why of homelessness is deeply embedded in structural factors such as the income gap between rich and poor and the crisis in the availability of decent, affordable housing, those who are most affected by these forces reflect our society's prejudices about who is most expendable. Just as in a game of musical chairs, someone is left standing when the music stops. As the characteristics of those left standing have changed over the decades, the record reads as a social history of our biases. Today, women, children, veterans, and persons with severe mental illness and co-occurring disorders are those we disregard the most (2,3).
