If you were to drive full time, that would get you about 27k/year, which is about the average income that a taxi driver makes. Rideshare companies are asking you to take more personal financial risk than you might as a taxi driver, but giving you more flexibility.
Still 27k/year is not much money really anywhere in the country. I think this is a symptom of some major underlying problems with our economy rather than an indictment of the rideshare industry. If we can't afford to pay drivers a living wage to do their work, then the people who are using these services aren't as well off as they think they are.
