I love the idea that, doing your job, and knowing about your job and doing training is treated like some kind of abnormal thing that suddenly deserves massive pay.
The training is simple, most jobs require you to train(to some degree, a lot don't have much training, but thousands of jobs have huge amounts of training). It's a few months of, press this button if Y, and do this if X and this makes it go forwards, this makes it stop, and red lights mean stop mkay.
It's not being a doctor, it's not several years of medical school and presumably... you actually get paid while training as it's you know, a job.
A doctor is highly specialised, does maybe 10 years of training all told and many people will be unable to pass that training. A train driver is not highly specialised, a few months of basic training that almost everyone on earth could complete doesn't make it a difficult job. It's not like they go for 3 months training and only a few come out the other side with newly gained knowledge of quantum physics and chaos theory. It's stuff no one else needs to know, but you do need to know to do the job, that doesn't make it complex or
