those who hire untrained screwdriver monkeys to do the
repairs,
No, those are 'trained service engineers'. Meaning they have been told to
follow the procedure in the manual without thinking what they are doing.
I was once asked 'Don't you think <foo> should be repaired by a trained
engineer'. My reply was 'No. I think it should be repaired by soembody
who actually understands how it should work and can find out what it is
actually doing. Not somebody who can just read and follow a manual'.
