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).
Yes, they lose some volume but Uber/Lyft is probably a pretty strongly engrained habit for many at this point.
Might be true in the valley, but I see no reason to believe that this is true in many other markets.
