Throughout my high school career, I see no drugs, no bullying
Sorry, but no.
If you didn't see bullying in school, you simply weren't looking hard enough or didn't know what you were witnessing was bullying. There is no country, no culture, no nothing where bullying in schools is not a thing.
As for drugs... Y'know, I went to American high school. And despite knowing who was likely doing them and had them... Do you think I saw them? Nope. Never. Because if I could see them, so could the teachers and staff. And kids would rather not be expelled and arrested, so they try not to be so stupid as to be seen with them. When it comes to things like that I think even in the most gang infested schools of Chicago or Detroit you'd still never (or shockingly rarely) would never see students, I dunno, shooting up heroin. Because as soon as that's visible, teachers are going to see it and you'll have the police and drug sniffing dogs on campus and the kids are minors and can't do shit about it and will be searched whether they like it or not. So kids, even though they are dumb, are rarely... THAT dumb.
One thing that I never saw in America (and would have been one HELL of a scandal) that does happen a lot in asian schools... Is
underaged "compensated dating" (Read: Prostitution). Gee, what could POSSIBLY be leading girls who are under immense stress, school education standards, social pressure and living in a highly conformist and regimented society to do something so outrageous as to rebel and go as far as whoring themselves out to old men to do so? Yeah, no teen pregnancy here, it's difficult to get pregnant if you're being paid to have protected sex with dozens of old men. That's... somehow... better, I guess.
no separation between the jocks, the cool girls and the nerds, every students are equal
I find this hard to believe. I think even most South Koreans/Chinese/Japanese people would be wondering where the hell you went to high school. Hell, most people in general. Because it doesn't matter what country or culture you're talking about - this happens. Shit, if it DOESN'T happen, that would be more concerning because this is how humans socialize. Meaning that this school is filled with students no longer acting human and no longer experiencing the human condition.
Kids in the US are just too free. The teachers and the parents can't control the kids.
Kids in the U.S. are no where near as "free" as you think. It's been over a decade since I was a student, but even then, schools were becoming more and more regimented and structured and not necessarily for the better because of it. "Zero Tolerance" regulations and rules are commonplace now. All I know is that if Japanese high schools are anything like what I'm getting an idea of them being like from people that teach there and talk about life in Japan and as a Japanese student... It would literal fucking hell for me. I already thought school was oppressive enough in America, especially in high school with the zero tolerance nonsense and how education was changing in just the short time I was alive. I think I would rather spend 3 years in Japanese prisons than 3 years in one of their more strict high schools. I'm not even joking there.
And, as demonstrated by things like compensated dating... It's not that the teachers and parents in asian countries control the kids... it's that they think, and are lead to believe, that they do. It's easy for a prison warden to pat himself on the back and proclaim he does a great job at keeping the prisoners in line and having them disciplined and controlled... As the prisoners quietly run the show as none-are-the-wiser. "The inmates running the asylum" is a saying for a reason... Hubris enters into this something fierce.
School shooting and teen pregnancy surprised me since they are things I didn't even heard of when I was in my old country.
School shootings are terrible, yes...
But school attacks are hardly unknown in China, either. Or Japan. Or Thailand.
I'm also unsure of why teen pregnancy is so surprising or upsetting as you make it out to be. Teenages are a chemical wasteland of hormones and, unsurprisingly, are horny and want to have sex. You thinking that you've disciplined them so well that they won't do anything is... pure and utter hubris. And it's getting to the point where if you told the Japanese government "the teens are not having sex and getting pregnant" they'd probably respond "WE KNOW! IT'S A HUGE PROBLEM!". Even though plenty of them are having
sex. They just aren't getting
pregnant. I can think of tons of things that are worse than getting pregnant as a teenager. And a lack of it is not proof that you have a controlled and disciplined citizenry.
My country has some sayings "Learn from a fellow student is better than learn from the teacher"
Maybe it's my shit-stirring American rebelliousness kicking in, but I find it ironic that in light of everything you advocated and defended about highly regimented, structured and respectful hierarchal society with an emphasis on strict education... You cited this at the end.
Not to say I disagree with it, but... It's just ironic to me.
