My kids, nieces, and nephews - and now a new generation - know where "the line" is, around here. They also know discipline flows freely. We don't beat, but a firmly applied attention getter is occasionally applied.
I've said for years that if you don't have a child's attention and respect, by the age of about 12, you're going to have problems for a long time (at least until the young person realizes they need to change, and some never do).
