I'm going to put an alternative view here. My guess is Uber has actually done enough legwork and figured out that contrary to these sob stories in the press, there are more than enough drivers that 1) have efficient vehicles that are cheaper to operate and 2) are willing to work for that profit in quantities to cover demand. If the rates Uber is providing drivers are so dismal they're protesting in the street, frankly, they should quit. No one is forcing drivers into a money-losing proposition. I'm especially unsympathetic given that they're paid on a per-transaction basis and there are alternative ridesharing companies out there. Those drivers can go work for a company that charges more for rides, and passengers who care about that can choose that option. The fact that passengers currently seem unwilling to pay for that (somehow we never consider it "socially responsible" that passengers are provided cheaper service...) makes me think that will be unlikely in the short term.
