When I was young I was always asked by people in school, "what are you going to be when you're older? Doctor? Lawyer? Engineer?"
I always found that strange, and remember replying "err.... there're many other kinds of jobs, right?"
To which I always got a "no! There're only 3 main job classes that are jobs worth doing" reply.
That's the kind of environment I grew up in.
Today after getting my diploma, honors degree and soon masters degree, I supervise grasscutting and ensure rubbish bins are cleared daily.
