Slate is hosting a discussion between Barbara Ehrenrich and Jason Furman on the issue of Wal-Mart and its effects on the working class. Furman is "a visiting scholar at New York University's Wagner Graduate School of Public Administration," and Ehrenrich pretended to be poor for several months and wrote a book about it. As Ehrenrich notes in the discussion, this isn't exactly a fair fight. As of Tuesday afternoon, Furman seems moments away from proposing the abolishment of the minimum wage. I don't know how long they plan to drag this out, but it's looking pretty ugly already.
