You just contradicted yourself.
First you said autimation is a terrible argument then you say people shouldnt be taking these jobs anyway.
If you think that's a contradiction, then you didn't understand the argument.
I'm not arguing that automation won't take jobs. They WILL take jobs. I'm arguing that they will take those jobs regardless of wages.
Also you do have to pay a robot wages because the entire industry is moving to a subscription based payment system.
Same logic still applies. Tech moves too fast - if the robot subscription costs $100/day this year, it'll be down to $60/day by next year to do the same work, and $40/year after that. You can't undercut it with lower wages because the tech is never going to be stagnant, it'll improve and it'll improve MUCH faster than a human without tech can improve.
You gotta learn to do things that robots can't do. You're never going to stay cheaper than one.
p.s. - this is also a good Basic Income argument, but that's for another time.
