semck - NO....it has everything to do with brain development, chemical balances, experience, etc etc etc. Your (childish) insistence that kids can be responsibile simply if we pretend they are is exactly the nonsense that comes out of kids that demonstrates they are not responsible.
The fact is, as a society, we are *far* more hands off of kids than we used to be, in terms of discipline, control, etc. Kids have far more leeway to act than they used to...and, I dare say, the results have not been impressive.
You used to drag a kid down to the principle's office and spank his ass when he got out of control. Now that's "abuse"...and instead of punishing the bully, we drag entire schools into anti-bullying assembly (taking them out of class), during which the bullies mock and snicker the speakers, and then go on about their bullying ways afterwards. We have told kids that they are entitled to everything, without expecting them to accomplish anything...and now our government thinks the definition of "kids" goes to age 26 - because that's how long lazy-ass Johnny will live in your basement sucking off your health care, instead of finding a couple friends, renting a small apartment and finding a low-paying job, which will eventually lead to a higher paying job, and so on.
No...kids clearly are not responsible. And I dare say those 18 years old in whos arms we shoved rifles and shipped off to war back in the 1940's would look at the pathetic state of youth today and spit on your shoes.
Yeah...that's about right, I think..
