You can shill for anything and get academics to jump on board, as long as you wrap it in the mantle of social justice. While this article is nominally ecumenical about postgraduate study, a disturbingly large portion of it is devoted to the question "How can we get disadvantaged students to take on nondischargeable loan debt and attend law school?"
