If so, then why are they choosing to work for Uber instead of doing whatever they'd be doing if Uber wasn't around? Are you saying that they're stupid or being tricked?
If not, then isn't the world a better place for those people with Uber as an option?
These people would have worked as taxi driver before, often with better compensation and job security.
But as soon as one person offers rates that are cheaper, all of them have to, or they won't get anything.
Uber drives competition between the employees, and as result, they all get less.
Simple economics. And also the reason that only unions and government regulation can ensure acceptable work conditions
Taxi drivers have earn like 30% less relative to before Uber, but there are 10 times more drivers that now earn about the same as the taxi drivers. That's a massive net growth of opportunities to earn money.
