Factory jobs involving repetitive motion can always be replaced by robots. They complain less, cost less, and don't go on strike when they're not sufficiently oiled.
Data entry jobs can be replaced by voice-to-text programs, and OCR programs for handwritten notes. These programs don't take coffee breaks or gossip by the water cooler.
Human Resources can go next. With sufficiently intelligent algorithms and a complete lack of data privacy, we can use job applicants' history on the internet to decide if they will fit in at our company now. And if the programs are wrong, we can just fire people. Doesn't take a whole department.
IT staffs are too expensive to maintain in America. And they're supercillious, antisocial, and whine like prima donnas when their toys don't work. Asian and Indian sweatshop programmers don't need a company cell phone or laptop, and they work for pennies on the dollar.
Truck drivers can be replaced by robot trains. We already have the tracks. We just need a system to tie it all together that can be managed by five or six folks altogether. It's not unreasonable to do -- model train hobbyists have had computer-programmed trains for decades. And computers don't drink, don't fall asleep on the side of the road, and don't get lost.
Cleaning staff can be supplanted by big Roombas.
News reporters can just be gotten rid of. We haven't had news reportage in this country for years anyway. In the future your news will be read to you by a digitally generated character.
Actors too. And artists. Nobody needs that junk. Or music. There's plenty of music in the world. It's good music too. All the music, books, movies and tv shows that need to be made have been made. Who needs more?
Mechanics can be replaced if we re-design cars to be built like Legos. You just unstick the parts you need to remove, and re-stick the good part back in. How hard can it be?
Gardeners will be eliminated in favor of plastic trees and astroturf. Easy peasy.
If you've come this far with me, you've realized that anyone's job can be disparaged. Anyone's means of living can be called into question. Anyone's worth to society can be put under an intolerant microscope and huffily dismissed.
But if you find yourself on the receiving end of this kind of attack, don't sit there and spin and justify yourself. Your employer already does so. Ask the motherfucker who dares question your right to participate in this economy where he gets off. Ask him if HIS job is sacred.
And ask him if the Koch brothers' latest check cleared. Because ultimately this frontal assault on the working American is coming from a pair of spoiled rotten silver-spoon jackholes who never had to wonder where their next meal was coming from. Inbred, blue-blooded royalty who has been pampered day in and out their whole lives.
