Against the race to the bottom? Uber sets the pace. Their rates are a low as possible to maintain a driver base.

There is a degree of debt in Uber atm because of this. Many drivers are not accommodating the true operating costs of their vehicles. They are using vehicles they had at hand, not one they purchased for the business. When those cars start to need replacement, Uber suddenly isn't paying enough. There is a reason many jurisdictions place limits on cab age. City driving for money simply destroys vehicles.
