That's a compelling argument, but I'm not actually sure I want that.
Uber's endgame is self-driving cars, which will put a lot more good people (Uber drivers and non-Uber drivers) out of a job. That's only feasible because of Uber's aggressive attitude to growth and crushing competition in long-term-unsustainable ways in the hope that the technology will materialize soon. If they change enough that this isn't their endgame or they don't pull it off in time, I don't know if they're financially viable.
I think that that goal and that pressure is part of why Uber is as rotten as it is (see how HR repeatedly doesn't want to fire abusive people who are allegedly high performers; even if the rest of their team would do better without them, Uber can't afford to figure that out).
Meanwhile, if they fail outright, it seems like basically all Uber drivers also drive for Lyft, and the engineering staff can get good jobs at lots of other places. It'll also be a good precedent for future companies not to try the strategy Uber has, and hopefully prevent more problems along these lines.
