RUFUS GRISCOM: Could you share with us your broader mission and how your new book, “Poverty, by America,” supports that mission?

MATTHEW DESMOND: I want to end poverty. I want to be part of the movement that’s growing around the country not to treat it but to cure it, not to reduce it but to abolish it. And I say that because we can. We can, as a country, put an end to all this scarcity and deprivation in our midst.
