Why is it that each generation keeps getting dumber and dumber?

My school is divided into two different campuses, called the junior and the senior. The junior is grades 7 and 8 while the senior is 9 to 11.  So last friday on 4/20 a student at the junior was getting help from a guidance counselor to clean his locker( the counselor helps students stay organized). When suddenly the counselor finds some weed in his locker. So already you can see why I think these kids aren't very smart, because he already knows that the counselor can say at any given time lets go clean your locker.  What makes this even dumber is that the kid then says "Well I'm not the only one with that stuff", like thats going to help his case.  So teachers started searching lockers and when they realized that they were finding quit a bit of drugs they called the police.  Then the police came in with drug sniffing dogs and searched all of the lockers. Around 12 students were caught with drugs in their possession and one kid even tried to say that the white powdery substance that was found in his locker was his sisters makeup!  And then after all of this a girl in grade 8 decided she would get drunk in class today.  Now if this doesn't sound dumb to you then your pretty dumb yourself.

But honestly what is up with these  kids its as if they have all gone back in time when people weren't civilized. Kids in grade 9 tell teachers to F off and they don't respect anybody besides them self, well actually they don't really respect them selves with the amount of drugs they do.  I've even heard that girls at the junior school bring boys into the back to give them blow jobs!  Like WTF we never did that when I was that age, they're 12 to 14 years old for god's sake!  There is obviously something going wrong with these kids and I think it's the parent's fault.  Parents are to easy on their children and instead of proper parenting there more worried about trying to be the cool mom or dad.  These parents are going to have to realize that there not going to be very cool when their daughter comes home nocked up or their son has an addiction to heroin!  But that's only my opinion.
