John Oliver gave a humorous spin to a very serious problem. Companies buy debt from the original creditors and then file lawsuits against the debtors to recover the debt, often times at interest rates that double, triple or quadruple the original debt. While perhaps not the focus of Mr. Oliver's show, he has identified a very significant problem concerning these debt purchasing practices. They are clogging up courts across the country trying to collect these debts, many of which were forgiven or written off by the original creditor years ago. Essentially, these debt purchasers have bought debt with the expectation they would be filing lawsuits to collect the debt.
