Uber is not a successful for-profit business in the long run as they make no profits; given free money to be able to subsidize what costs there are (and operating on the backs of people who make little themselves) can exist for a long time before failing. In the meantime richly paid executives and well paid employees can milk it for a long time.
Exactly what I was referring to. The whole business is broken, it is merely a bet on removing worker rights in the long run and that is what it is valued for.
