Oh, yes: You have beautifully described one of a parent's (particularly a father's) duties. I have no trouble believing that you did so diligently and successfully, and that your grown children are a credit to you and your wife. I say that with all sincerity.
Furthermore, based on direct experience, I believe that you are not as rare as some people might suggest.
HOWEVER ...
Based on entirely too much direct experience I KNOW beyond a shadow of doubt that a critical mass of "parents" absolutely refuse the duty of raising their children properly. Even one of these ill-bred, brought up wrong and trained to do worse, little junior-grade thugs can and will turn a classroom into chaos. Calling the little wretch's parent (frequently only one) is useless ... worse than useless, in fact. Little Suzy/Johnny can do no wrong ... (s)he is a perfect angel.
If the student’s parents don’t take action, then suspend/expel
I'm laughing again. That's great in theory. In practice, it doesn't happen.
Like many other institutions in this Great Republic, formal education needs a thorough top-to bottom overhaul. Classrooms should be the domain of students who want to learn and teacher who have something useful to convey. Compulsory education laws should be repealed as part of that overhaul.
Well, you’re right that my kids have done well - all degreed except for the two in college now and I’m proud of them. But like I’ve said, we did our part.
The three biggest problems of educational system are:
1. Everything is aimed at the lowest common denominator- no more separated curricula for Honors, College Prep, and General Education. Everybody Is lumped together, including emotionally disabled kids.
2. The teachers unions are corrupt, Leftist, and powerful - and infested with perverts.
3. Parents are not held accountable. They should be the ones to feel the wrath of the law if their kids don’t behave.
Probably not the dungeon, though.
