It also sends a message that there’s no point in bringing up things that bother you. A kid raised on “just ignore them” may internalize that they shouldn’t talk about their problems, since nobody’s going to help them anyway. Then someday they may end up in a work force where they don’t bring up issues to management that could totally be resolved with a simple conversation. Worse yet, if they have a beef with someone and the other person speaks to management first, they’ll immediately be put on the defense simply because they didn’t say anything sooner.
