Where I am from, if you disrespect the teacher, you get whipped; and parents are not even allowed to enter the school.
I'm from South of Russia, from a Cossack community. In our lands, you walk through a school, all you hear are sounds of pens and pencils writing, teachers talking, and children only speaking up if asked something by the teacher.
All adults in our society, teachers included, carry a nagaika and do not hesitate to use it on a insolent youth. It happened to me a few times, and it hurts like hell itself. Very, very effective.
No, where I am from, you do not see drunk, disrespectful, rude, arrogant youth. When a elder walks into a room, if any young ones are there, they stand up, remove their hats, and bow.
In the street, you do not pass an elder who is walking before you without asking permission, it is rude.
On public transport, you would see, an elder comes in, on a bus, or a commuter train, even if it is not full, young ones right away jump up to yield their seats.
Discipline, respect, culture, it is beaten into you from a young age where I come from. And we are proud of that. The rest of Russia envies us for our ways.
