Yeah, that's always been one of my points: existing cab fares are probably already close to the the price to sustain a business and pay a living wage.
Like you said, cab drivers (and probably cab company owners) aren't exactly fatcats. Meanwhile what's Travis Kalanick's net worth? How much are they paying top engineers at Uber?
Don't get me wrong, there's definitely corruption and protectionism in the existing taxi industry, but I fail to see how the low $5-7 fares are anywhere near sustainable. Is the revenue from surge pricing enough to offset the current discount?
