Ocker,
Sir, what you seem not to realise, is that we are paid not for what we do, but more for what we know, and how we can apply our knowledge to whatever situation we may find ourselves in.
Same as a trucky, he/she has knowledge about his/her machine which is pertinant to any situation they may find themselves in.
If you should ever venture into looking at the training we undertake, you'll find that we're all in fact aviators, doctors, lawyers, meteorologists, physicists and mathematicians all rolled into one.
Does that talk us up enough?
