Another licenced engineer here, don't have time to write much at the moment, but Yogi has a point about the quality of some engineers. However, to say two thirds are incompetant displays either a lack of knowledge on the subject or just a severe problem with basic arithmetic.
Obviously I consider myself to be competant, with the responsibilities we have in this job, not too many people who aren't sure of their abilities would be able to go to work each day.
As often happens, the fly-boy has his head in the clouds (pardon the pun). He obviously thinks he has a right to look down (pardon the pun) on us lesser mortals. What next? Trolley dollies also getting ideas above their station?
Surely not.
