Depends on the relationships of the parents and children .If the kids are total a$$holes they will be on the outside looking in. Can't blame the parents for how kids turn out . The best parents end up with kids who are out of control many times . Peer pressure and Madison Avenue are a big factor in what kids do away from the home nowadays ( as well as the propaganda left leaning educators .)
Uh...no. Bad parenting is the #1 cause of bad kids. Good parents will find ways to get their kids under control even if they have to resort to tough love and will say to their kids "If everyone else jumps off a cliff, will you?" - Madison Avenue can be overcome.
If parents are totally blameless, my relatives will stay in business for a long time teaching remedial education. Not a problem for them. Let the bad parenting continue....and we thank you for your support.
