It is a stunning indictment of the educational system, the astonishing stupidity of so many of those who emerge weighed down with its prizes. Having 'won', they naturally assume that the basic game, and all its rules, are sound; and, by extension, that the failure of the 'failures' is the failures' fault.
I've never forgotten seeing one of those reality tv series, where they recreated a secondary modern school. Without getting into the bigger argument, much less going all misty eyed about the past educational system (which I suspect was overall, in truth, worse than the one we have now), it was striking how eagerly many of the assembled kids (chosen on account of their current 'failure' status, and hence precisely the kind of 11 plus-failing kids who would have gone to a SM school) took to things like bricklaying, and car mechanics.
They really, positively, enjoyed it. Hands on doing stuff, rather than sitting in a classroom while all the 'clever' kids left them behind. They thrived on it. Both the doing of it, and the doing of *something* that they found they were good at, that they could succeed in, and that - not least - they knew was clearly leading them toward a future in which they could have an identity, a role and a status, and be sure of a roof over their head and enough cash to keep worry at bay.
Why do 'clever' people assume there's only one kind of clever? Because it's the kind of clever they happen to have. Idiots.
