What I noticed about China is that they employ a lot of people to stand around in nice looking government (non-police) uniforms and do various menial work or not much at all.
The US does this to a perhaps a lesser extent with jobs like TSA agents.
Sure, I guess you can do UBI, but what if that’s less efficient overall?
Example given with made up numbers:
Status quo, an Uber driver makes $20/hour out of a revenue of $50/hour total covering vehicle operating costs and platform fees.
Self-driving cars: self-driving cars cost $40/hour to operate, UBI pays someone a wage of $20/hour since there’s no job available. This basically means that rideshares now cost $10/hour more to operate than before.
Or, maybe that person on UBI makes $10/hour instead of $20/hour and gets a worse job to cover the difference.
Obviously there are many flaws and assumptions with the way I present this scenario but it’s a really good question to bring up whether putting everyone out of work is actually going to be a net positive.
Regarding what you said about driver hours, it’s not unheard of to run multiple drivers on multiple shifts with the same vehicle. Not all rideshare drivers own the vehicle nor use it as a personal vehicle. But the other factor is that the drivers who do use personal vehicles effectively subsidize the fact that they can only drive it for a human-length shift. Waymo has to buy every car (more expensive than a normal car) and use it only for business purposes while an uber driver can just use the same used Toyota Prius they use to take their kids to soccer practice.
