One of the fundamental points about going to school is to be taught well enough to be able to go out into the world and either get a decent, satsifactorily remunerated job, or the means to support oneself in another capacity. The former then becomes the quest for a good honest career – a job for life it used to be thought of. If we look back to our own childhoods, earnest relatives would peer down at us and demand to know what we wanted to do when we left school. Most of us at aged 8 or 9 were not in a position to say – none of us had much grasp on life outide that limited school experience. Very often we would stab out an answer, which in all honesty was probably a job our parents would rather have liked us to take up when the time came. Young Nancy wants to be a Nurse like her Aunty, or Derek fancies being a bus driver, etc. etc.
These days they do need to have such wits about them as soon as they get into Years 3 or 4 at Junior school, so they are put into the stream that governs the type of final examinations they will be taught to enter said chosen career. Be that a doctor, lawyer, juddge, nurse, banker etc etc. The top schools have a rigid system built up over centuries, that send their student out to the right universities and colleges.
