If a company can't both sustain itself and its employees financially, surely that's a failed business? If the only way you can survive is by exploiting the poor, maybe you should be rethinking your strategy.
I think a lot of those people wouldn't have jobs otherwise, is something better than nothing?
Also it's not just the poor, I've had many friends use uber as a stop gap between jobs. One of my drivers had a masters in Finance - I don't see anything wrong with gig work as long as both sides know what they are signing up for.
Why would they be out of a job? Surely bleeding money in Uber’s case is a self-inflicted wound, because they provide a service below cost? Raise prices, problem solved.
Oh wait there are other companies that also follow the same model and Uber would lose all customers the moment it raised prices? Looks like something in the rules doesn’t add up unless VC money doesn’t stop flowing.
