Are kids worse now?
I think so
I was 11 when this movie came out and could have been a slightly younger version of Carl. As I got into my teens in the early 80's the first 3/4 of the movie could have been biographic
Still we partied a lot and while there was the occasional boxing match, noone ever got killed, the whole drunken date rape thing was rare, and few if any of us turned out to be criminal thugs.
The average kid didn't go to juvenile hall, and teenage pregnancy happened but it was still rare. All in all I think we handled things much better than the movie portrayed. When you compare that time to now, where kids get shot over rap songs, and the average girl is a welfare broodmare, and the average boy is an effeminate whiner, I think we did pretty well.
