Here in Malaysia, younger and older locals seem to be quite happy with it. A lot of the older drivers do it for some extra "coffee money" when they get bored. The younger do it full-time, part-time as a student in college, or just a full-time job.
Uber has also been pretty good for the entrepreneurs in KL. Start up drop shippers, content writers, and free-lance programmers use it to sustain them while they pay for their setup costs.
