It's interesting seeing what people have to say on this topic. I can't speak for other regions of the country, but in my district of Hawaii, the "serfs" who lose jobs due to mechanization have zero opportunity to find another job.
Two large macadamia farms switched to mechanized harvesting, causing dozens and dozens of people to lose jobs. The local coffee farms are talking about going to mechanized harvesting and robots & machines to do the rest. Dozens and dozens of jobs will disappear. The country bought a street cleaning machine and also now uses herbacide for weed control along the roadsides. Thus street cleaning and weedwacking jobs disappeared. A local business that use to hire unskilled workers is shutting down and moving to Hilo.....thus the loss of over a dozen low level jobs. These "serfs" have no jobs to move to.
My area has no vocational training or adult education. "Serfs" have no opportunity to acquire new skills so that they could qualify for some other job. Add to that, county regulations that make it quite difficult, complicated, expensive, and sometimes plain impossible to start your own small business. So what happens next? The area gets more and more people just hanging around. Theft increases. Some people resort to selling drugs to make some money, thus drug use increases, and the crime that goes along with it. More people go on food stamps. They can't afford rent, moving in with relatives or squatting on vacant land in tents or garden sheds. Thus local landlords start finding their houses empty, and thus switch to vacation rentals. But alas, the county in its wisdom just passed new laws making those rentals illegal or expensive to register.
While business benefits by mechanization and robots, and consumers might see prices stay acceptable, the "serfs" lose big time. This loss trickles down to hurting the community. I'm seeing Walmart and other big stores switching to robot floor cleaners. I see most big stores switching to self check outs. This all means loss of untrained jobs.
In my area, the public schooling adds to the cascading problem. Kids graduate with zero marketable skills. Zero. So unless they move out of the area, they join the unemployable population.
Personally I'd like to see lots of small businesses start up that hire the unskilled worker. But alas, Hawaii's regulations make that unrealistic. I'd also like to see a vocational training school here, but that's not about to happen either. So as the established businesses mechanize and incorporate robots, I see the serfs losing.....at least where I live. Face it, there are only so many Walmart greeter jobs or supermarket bagger positions available anymore.
