It's an example. Things like youth clubs are mainly things for the youth of tomorrow. For the kids who are already 16/17 then you need to take a different, harder approach I feel.
But to stop this from happening in the future, you NEED to give the younger generation things to be proud of. Offer more activities in school, get them focused on their future etc.
I honestly believe that school needs to be an extra hour or two, and those hours teaching kids to be proud of themselves instead of just education.
I also believe that school holidays should be no longer than two or three weeks at a time.
