Mum's real bugbear was the students she had to take round on a regular basis. She always complained that they weren't interested in learning how a job was done, and when she asked them why, their standard reply was "oh, we want to do a degree and go into management."
So yeah...
But then as an engineer who was subjected to various management courses, my point is this: how can management "manage" if they've no idea about the work people on the front line actually do. How it's done, the time it takes to do it properly, and what you need for the task in hand.
