Uber will remain here and their rides will stay cheap. I am, however, very concerned about their drivers. Many of them are making huge investments purchasing new cars with the implicit (and sometimes borderline explicit, depending on the marketing rep you talk to at Uber) that they can have guaranteed work and a guaranteed wage. If über decides to cut driver wages in half and pocket the profits, drivers will be out of luck. This can be catastrophic for poor families, which will be basically be forced into wage slavery. This will have huge effects on the community as Uber gets bigger.
We can all point to how Taxi unions and their lobbyists are evil (as a colored man, it's difficult for me to get picked up by one), how awesome Uber is w/ their investments in autonomous cars, and the free markets are great...but we need real employee protections in this country.
We need real protection for drivers who are making a huge investment. This doesn't have to hurt consumers either, as über can still remain insanely profitable while maintaining lower prices.
