When I was at school, we moved from junior school up to either grammar or secondary school based on the eleven-plus exam. It was called that because you took the exam when you were eleven or over.
Later, grammar and secondary schools merged: you still took the exam but went to the same school anyway. The exam determined which class you went into. That was the beginning of things like 'no child left behind' and other ridiculous anti-intelligence legislation.
Now, it seems, the logical conclusion is upon us. No child is to take any kind of exam until they are sixteen. There will be no differentiation, no nurturing of future Einsteins, no diversion of those who just can't do academia into more applied (and incidentally, often more profitable) lines of work.
True homogeneity awaits. IQ tests will go next, along with organisations like MENSA, which will be deemed elitist. The future is bland. The world anthem will be 'I am the Walrus', with its prophetic opening 'I am he as you are he as you are me. . .'
John Lennon saw it coming. Soon we will indeed be the eggmen.
