Society is made up of humans. The economy in your case is the tail wagging the dog.
The problem with your train of thought is that it isn't sustainable. When people get fed up and start burning ubers, the folks betting against people will be the ones finding their backs on he wall.
How many people has the US military killed over the last 10 years? How many US military personnel have been killed? The ratio is on the order of 100:1. (I'm not making any kind of moral judgement about the US military here, just pointing out it's raw effectiveness at a core competency, which is killing without being killed.)
People are not a great bet in the present technological era.
People matter.
So your argument is preaching to the choir not to that which you need to convert which is technological progress.
You are simply confusing what humans need with what humans can expect. Technology is a competitor to humans not just a tool.
My train of thought is exactly sustainable in that it expects technology to take over most jobs instead of ignoring this.
If people start burning uber cars then uber cars will start defend themselves. Again technology is competitor way before we take it into Superintelligence land.
If more people was on my "train" we would be dealing with the problem by introducing something like Unconditional Income.
Technology is like a tsunami, you can try and stop it or try and learn to surf on top of it for as long as possible. I prefer the latter rather than being crushed by the former.
People make laws. People make technology. If we continue down a path of making technology only serve the accumulation of capital, people will course correct the direction of technology.
In reality technology makes it possible for less and less people to increase their output and span of what they can control via technology.
Some day a few people will be running large systems that requires only drones, AI's and access to resources to create what today takes millions.
By insisting on keeping humans where technology is much better suited for the job we are damaging our own economy because we are creating an artificial reliance on human capital where it's not needed and thus increasing the price for everyone.
This is obviously a huge problem as more and more people will be making less and less income. The only way to mitigate this is by products being increasingly cheaper something that a job-centric economy is hindering.
We should be honest and admit that the Uber economy is a mirror into this reality where the competition heats up, driving prices down and incomes down until self-driving cars is completely removing incomes for working people.
And if you claim like many do that technology creates more jobs than it produces then you are not only wrong you also need to show what new areas you are expecting the millions of people who are already made obsolete to the job market because of technology.
