Ill add that at work sometimes im I get to do job interviews for the warehouse I work at.
Most of them are young kids in their teens.
I can tell within 5 minutes if the kid has had good disciplined raising or not. I wont go as far to say they are all bad either, cause weve had a few come through that mom and dad did a fine job with. These kids almost never miss work and do well with quality and quantity of work.
You sure remember the ones that dont though. I believe some were raised by nintendo, and their bodies and minds show it!
