A very erudite post J52.
Except this bit...
think carefully if you still want to be topping up oil, kicking tyres and checking for cracks 30 years from now. Very few of you will get a career fulfilling job of any type and even fewer will make it into management.
Most of us find "topping up oil, kicking tyres and checking for cracks" quite fulfilling enough and have no intention of applying for a management position.
You're spot on about the money though.
