The end game for many Uber drivers is poverty. They don’t earn enough from driving to make a living. Uber is not alone in this. Its competitor, Lyft, has the same challenge. This presents a PR problem for both companies. If drivers become convinced that ferrying passengers is a mug’s game, they will no longer do it. Then where will the two services be? Statistics show an extremely high turnover in drivers per year. On the other hand, if fewer drivers work for both services, their average income will rise and they might make a living. This would lend credence to limiting the number of drivers in a region to make sure they can survive. So far, neither service has appeared to do that. High tech is not always better.
