>Uber is a bad example because it's losing billions every year.

IMHO, that's what makes it a good example. It can only make money by driving its drivers' wages well below what they themselves will accept or what competing, traditional taxi companies currently pay. With the spigot of VC cash turned off, Uber is exposed as having little viable business model besides straightforward exploitation. There's basically nothing innovative or original about them that lets them make money off nothing but an app for coordinating other agents' labor. The drivers are either incredibly exploited wage-workers or independent contractors who therefore don't need Uber, but can't be both.
