When those gambling sites are already been pointed at to be luring the children into gambling, it is something the school needs to take action on and not categorically stating other things that can make the student performance poor in the school. Those are all known facts and the government or the school management may have taken the big picture of it and finding solutions to that, those are general problems faced by any nation’s school. In this case, the OP stated what the gambling companies are after and how they’re making students been deviated from their studies and to the extent of using their tuition fees to gamble. That’s too much to say and these gambling sites should be regularized for such jurisdictions to avoid further harm to the students academic reputation.
It is not children but adults. The students are not from kindergarten, nursery, primary or secondary school pupils but university students so they are not children but adults. And gambling is not for children but for adults from 18+ years. So when you're making comments here in the thread carefully select the words. Any person above 18+ is no more a child. I have said it before and here again.
I understand your point and even if the persons in this case are adults, the government wouldn’t just watch away them useless their precious time in school through involvement in gambling activities. The statement might be an idiomatic expression but it is passing a message for them, the ones that will listen will take the right action and the ones that won’t, will likely fall more victims to it. The government has the power on itself to ban the activity of the gambling companies even if they’ve clearly stated that it is for adults and only adults engage in them. There is a degree on how that can affect the whole varsity students and it will force the government to take action. Nothing is above the government power and anything can force them to take action. I know adults are only allowed to gamble and the government can only advise them but they can also do otherwise to stop the spread if it’s causing more harm than good which may also likely affect their governance overall when it goes on a larger level.
