Peer-to-peer lending was supposed to disrupt the traditional way people borrowed money. Instead of going to some giant, soulless institution, online platforms offered a way for people to post what they needed to borrow money for, and for other individuals to loan them the money. In other words, rather than have a bank match up savers and borrowers, why not just cut out the middle? But as the industry has grown up, it looks more and more like the old establishment firms it was trying to disrupt. And now, the industry faces an old-school scandal. This week, Odd Lots co-host Tracy Alloway (who is an expert on these firms) explains how it all happened.
