Where can those children go?
I think a lot of students going to such type of second or third tier schools would not be able to get a place at another decent school.
Of course, what else can they do?
This is a second or third tier school. Children are mostly not able to transfer to other "good schools". So the only way is to accept the situation.
I am sure while some people seem to be so supportive, many parents are now silently working their way to pull their kids out of the school. Those that can afford the fees may even have to consider school in another country.
