The system by which the college is funded means that it literally cannot afford to exclude students, even if it wanted to. Resources are allocated to colleges on the basis of how successfully they meet targets on achievement (exam results), attendance and retention of students. This combination of market imperatives with bureaucratically-defined 'targets' is typical of the 'market Stalinist' initiatives which now regulate public services. The lack of an effective disciplinary system has not, to say the least, been compensated for by an increase in student self-motivation. Students are aware that if they don't attend for weeks on end, and/or if they don't produce any work, they will not face any meaningful sanction. They typically respond to this freedom not by pursuing projects but by falling into hedonic (or anhedonic) lassitude: the soft narcosis, the comfort food oblivion of Playstation, all-night TV and marijuana. Ask students to read for more than a couple of sentences and many - and these are A-level students mind you - will protest that they can't do it. The most frequent complaint teachers hear is that it's boring. It is not so much the content of the written material that is at issue here; it is the act of reading itself that is deemed to be 'boring'.
To be bored simply means to be removed from the communicative sensation-stimulus matrix of texting, YouTube and fast food; to be denied, for a moment, the constant flow of sugary gratification on demand.
