Ride share, by the strict definition, is just the point of entry. Uber's goal is to become transportation infrastructure, in a 'privatize the gains, socialize the losses' kind of way, as with the rail barons and the car companies and the commercial airlines.
Why do you think they’ll manage to socialize the losses?
So far the losses have been very privatized (VC and bank money) and if anything the gains have been socialized (the general public has benefited a lot in the form of taxi-like transportation, airport rides, etc. getting phenomenally better in most cities where Uber exists).
There have also been public losses. Transit ridership tends to decrease with increased ridesharing. This means more cars on the roads, less money for public transit, and more pollution.
