Sorry for the cut-n-paste, but this isn't new. This is from C.S. Lewis' "Screwtape Proposes a Toast", written in 1959.
For those not familiar, Screwtape is a fictional demon (we hope), whose voice C.S. Lewis used to make certain theological points (in an inverted fashion, of course). This is an excerpt from a sort of postscript to his book The Screwtape Letters.
"At universities, examinations must be framed so that nearly all the students get good marks. Entrance examinations must be framed so that all, or nearly all, citizens can go to universities, whether they have any power (or wish) to profit by higher education or not. At schools, the children who are too stupid or lazy to learn languages and mathematics and elementary science can be set to doing the things that children used to do in their spare time. Let them, for example, make mud-pies and call it modeling. But all the time there must be no faintest hint that they are inferior to the children who are at work. Whatever nonsense they are engaged in must have - I believe the English already use the phrase - 'parity of esteem'. An even more drastic scheme is not impossible. Children who are fit to proceed to a higher class may be artificially kept back, because the others would get a trauma - Beelzebub, what a useful word! - by being left behind. The bright pupil remains democratically fettered to his own age-group throughout his school career, and a boy who would be capable of tackling Aeschylus or Dante sits listening to his coaeval's attempts to spell out A CAT SAT ON THE MAT."
