Jon,
First, congratulations tto your daughter on getting started on a good career path. It's very difficult in today's climate whether you have a degree or not.
"Just because they have spent 4 to 5 yrs at Uni dont mean they can do the job, they have never worked. Further to that no on the job training"
I don't think you are familiar with modern engineering degrees. One reason for them now being 4 to 5 years is that the course includes a year workig in industry. In one of my previous jobs I took engineering students for their industrial year and I made sure that they got the necessary training. Perhaps yet more could be done. At the top engineering university in France they have about 2000 students but only 1000 are on campus.
The exams for engineering degrees do not just require the regurgitation of facts learned from books but the application of those facts to solve problems.
"Certainly my last job there has never ever been any books written, just the odd snippet of information which is mostly incorrect! Taught by the last working person who in turn taught by his dad and decendants. Of which only three of us alive in the world, no books will ever be written its a guarded secret that will be taken to the grave."
This seems to be a very selfish attitude. If your skills are really so exceptional why are you not making the effort to pass them on. Perhaps you could enlighten us? What are these skills?
Finally, if you really think theory is so useless, consider the following examples:
In the middle of the 19th centuary a mathematics professor, George Boole, developed a form of algebra for analysing logic, later known as Boolean algebra. It had no application at the time but without it we would not have been able to design computers.
More recently Albert Einstien developed the theory of relativity using only "thought experiments", no practical tests at all. Without this theory we would have no nuclear energy and no accurate GPS system.
Later quantum theory was formulated by a number of theoretical physicists. Without quantum theory there would be no modern electronics.
I could go on but I think the point is made that we need a balance. We need theoreticians, professional engineers, craftsmen, technicians, etc. Few theoreticians can do the work of craftsmen and vice versa.
