Well Uber, is a good way for people to create/supplement their income with a relatively low starting cost.
The problem with today's economy, it is too tough for the average citizen to work to control their income, If they work part time, they get unpredictable hours so they cannot get a second job, If they work full time, they are either salaried or forced to work their hours.
Our IT infrastructure, has created many good Starter jobs (Mail Room) obsolete, So you will need to be skilled in order to get in.
I will need to applaud Uber, as its business model, allows for people to work for their money, the harder they work the more they get paid.
