I wouldn't exactly consider these as "jobs" either. I would agree that it is independent contracting. But so what? Uber has made it possible for thousands of people to use their own vehicles to expand their opportunity to earn money by engaging in the transportation of people for commercial purposes. Prior to Uber, that would have been very difficult.
Reich is engaging in philosophical pissantry. Just another sneering elitist.
The sharing economy as exemplified through sites like Uber is a helping hand up for those unemployed and under employed, but it does not replace the sheer loss of jobs through globalization and formal economy replacement of citizens by illegal immigrants.
