Ironically, OP is the one arguing as if he is 100% aware of job of driving an uber and his awareness leads him to argue that it is categorically bad.
More realistically, it is good for some, bad for some...like basically any other job.
You said people are leaving existing jobs to drive for uber.
My response is that people make bad decisions all the time. That doesn't make the decision any less bad.
Also, based on most research, driving for Uber is generally nowhere near as well paying as they imply it is, when all costs are taken into account.
