I agree with everyone else, raising the drinking age won't do jack. Besides, kids are already underage drinking, what would an age limit do? There would just be more underage drinking anyway. People have put drinking in their everyday lifestyles, some even coaching themselves how to go into work drunk/hangover. It'd be like how most people quit smoking, you can't just say 'I won't do it anymore' and everything will be fine.
As a 'youth of today' I know how bad underage drinking is. And I'm shocked that the statistics say '10%' because I can tell you, that 70% of my year level binge drink on the weekends. I'm literally not exaggerating, however my school does have the worst reputation out of all the schools in my area.
Most reasons why I think it happens have already been covered. Parents allow it, it's in fashion to do, peer pressure, role models, the way our lives are etc.
But I can also tell you most youth today are educated about the dangers. In health, we had to do 6 months about the dangers of alcohol. But these kids still go out and get pissed every weekend. I actually know people who don't just binge drink at parties or when they're out with friends, but they get drunk in their room alone, when their parents are in the loungeroom watching television.
I think it's not the education side which fails, but the fact they think they're immortal and liver damage doesn't happen to young people, just old people who go to the pub every Friday night and are old and about to die soon anyway.
This is becoming quite a big problem now. Sure they might just be a bunch of kids getting drunk now, but what happens when they get their license? What if they get into a construction job and because they've taught themselves to deal with a hangover or being drunk, they operate machinery under the influence? Actually, it doesn't even have to be construction. Factory jobs have machinery you have to work too. Now I'd hope people wouldn't be THAT dumb to turn up to work while using a big slicer or something, however I have family members who have.
It's not just their own personal safety of ruining their bodies, or getting violent on public we have to worry about. There's a whole lot of other things too.
The best way we can deal with this is to evaluate our lifestyles. Parents, if not already should be more weary of where their children are Saturday nights, and who they're staying with. Children don't like their parents being overprotective, but sometimes they just have to be. I think a lot of parents aren't aware of what their kids are doing or who they're with, and would be shocked if they knew.
In health classes, don't just have a quick lesson or two about it. Even then, give a more personal approach. Just doing a few worksheets isn't going to scare anyone into not drinking. Bring in a guest speaker to talk about how alcohol affected their lives.
Just those two examples would help cut the percentages of underage drinking in half, which would also help young adults who are legally allowed to drink and abuse that by binge drinking.
