If having less work that needs to be done is a negative then there's a problem with our system of economics, not with having less work that needs to be done.
Truck driving is not and has never been a middle-class occupation.
Thats perception. Most o/o's are firmly upper middle. It's the hired drivers that get shafted, but even they do alright.
More automation is a win for the middle class and every other class. If a society chooses to violently deprive the middle class of economic resources, that's the fault of the police, not the automated economy.
The police might enforce the legal code of a system the funnels economic gains to fewer and fewer people, but they don’t come up with the ideas on which that system is based.
