The problem is particularly serious in some countries, like South Korea.
A recent popular Korean tv serial "teach you a lesson" became wildly popular despite being not-so-politically-correct, precisely because of the severity of the problem.
Wild how much of the successful entertainment coming out of South Korea (like Squid Game), is basically them dramatizing facets of their dystopian society, that a lot of it is actually based on real issues they face, and it's not all just made up fantasy.
Indeed. I haven't been to Korea but when I was in China, I met many Koreans and when I was taking Chinese lessons, some Koreans were in my class.
They are generally less friendlier than all the other foreigners I met, closed to outsiders, and somewhat racist (I asked a group of Koreans if I could join their game of Basketball, but they said they preferred to play by themselves. No Chinese ever said anything like that, nor any other foreigners I had joined to play with).
Also, they are quite a violent people. My classmates and I nearly came to blows over the window in the class; I wanted to open it because the indoor air was stale and probably toxic, but he didn't want the window open (for whatever reason, though the weather wasn't cold). Another non-Asian foreigner got into a fight with a Korean puncturing his eardrum which resulted in deafness. Outside the university, too, when they get drunk they become aggressive and seek fights. I guess it must be all the stress they're to put up with in their Dystopian country?
