Not sure I fully understand your point Theland. Firstly, it is likely, I would have thought, that those studying Shakespeare are probably doing well academically anyway;
And second, is studying Shakespeare a large and time consuming part of the curriculum anymore? What would not be a good idea would be to ditch everything seen as peripheral to such things as numeracy, IT etc.
Finally, Shakespeare covered just about every human relationship and situation in his works, and was responsible for some of the most apt and memorable phrases in the english language. I would say his works are part of our cultural DNA...
