Case in point: I was in India (Chennai) for a week on business a couple of months ago. During that time (M-F), I had a driver who was dedicated to me. He took me to the office and back, and took me anywhere else I wanted to go. This wasn't a taxi service, he had nobody else to shuttle around. When I was working, he just waited around for me to call. The cost for all of this? US $25, for the entire week. That's what I paid the car service, so he's getting some amount less than that.
All this to say: These sorts of comparisons are not as dramatic as they seem.
