Everyone is walking around with devices that connect them to nearly the total sum of human knowledge. Not acting on that to get out of an easily replaceable job is a skill issue. Also, the education systems currently aren't the best. Automation and IT hasn't penetrated them as much as is feasible.
"To each according to his ability. Everyone else suck shit."
Nowadays it's easier to learn than ever, and the real rates of intellectual disabilities/neurodiversity hadn't gone up that much. Such conditions are just easier to diagnose nowadays.
Thus yes, if you won't learn, and you can't prove that it's an organic problem, enjoy a job that sucks.
Blaming capitalism for that is meaningless.
