We have a society where we try to incrementally move minors into adulthood. If the legal drinking age were 16 I think we'd see a lot more drop outs and more alcohol abuse. We don't take them into the military because we want to educate minors.
Recruiters get into trouble for things like forging high school diplomas.
These things shouldn't HAVE to be explained!
Thats my point.. They arent ready yet.. They dont have the brains to do it. Again why only treat them as adults when they do something bad..
