I look at it this way, why would any politician with an artificially elected guaranteed seat would agree to face actual 'HARD TALK' in an extremely face-saving society!! Unless it is semi-hard/soft-hard talk without crossing that invisible and now rapidly changing boundary..
For those interested in more stats ...
Seems like the top end band A schools around town are seeing a 10%ish withdrawal rate of students.

Yeah, I can confirm that my school (one of the top Band 1 schools) has lost close to 10% of students. Owing to the fact that most of our students come from a lower socioeconomic background than the average HK family, I would assume that this number would be higher if these students' families had more opportunities.
