A group of Occupy Wall Street activists has bought almost $15m of Americans' personal debt over the last year as part of the Rolling Jubilee project to help people pay off their outstanding credit. Rolling Jubilee, set up by Occupy's Strike Debt group following the street protests that swept the world in 2011, launched on 15 November 2012. The group purchases personal debt cheaply from banks before "abolishing" it, freeing individuals from their bills. By purchasing the debt at knockdown prices the group has managed to free $14,734,569.87 of personal debt, mainly medical debt, spending only $400,000. "We thought that the ratio would be about 20 to 1," said Andrew Ross, a member of Strike Debt and professor of social and cultural analysis at New York University. "In fact we've been able to buy debt a lot more cheaply than that." The Rolling Jubilee project was mostly conceived as a "public education project", Ross said. "Our purpose in doing this, aside from helping some people along the way - there's certainly many, many people who are very thankful that their debts are abolished - our primary purpose was to spread information about the workings of this secondary debt market." The group has ... acquired the $14.7m in three separate purchases, most recently purchasing the value of $13.5m on medical debt owed by 2,693 people across 45 states and Puerto Rico, Rolling Jubilee said in a press release. "No one should have to go into debt or bankruptcy because they get sick," said Laura Hanna, an organiser with the group. Hanna said 62% of all personal bankruptcies have medical debt as a contributing factor.
