"In 2014, Strike Debt bought $3.8m worth of students’ loans, and spawned other ad hoc initiatives: in 2016 TV host John Oliver bought and wrote off $15m of medical debt held by 9,000 people. The Rolling Jubilee campaign has raised over $700,000 – enough to buy back over $30m debt." (https://www.theguardian.com/world/2018/mar/23/hoe-street-central-bank-walthamstow-london-debt?)
