Chaebol - basically your typical cyberpunk megacorporation is real. Samsung is such a huge factor in our economy that if it were to fail our country would collapse. This is what happens when you invest in a few big companies to drive you to the top.
Materialistic desire - lots of Koreans have an unhealthy view on society. You must be rich, you must be attractive, you must wear good clothing and drive an expensive car. You must own a good house. A lot of success depends on how much wealth you have. Either that, or it depends on how academically proven you are (notice how I didn't say smart, or intelligent - Korea's education system is quite dependant on memorisation over critical thinking. I got a 1580 on the SAT and attend a prestigious university in the States, yet if I were to have applied to Korean universities I would probably be attending some third-rate college in a rural area. I also attended public school in Korea, so I was not at all likely to apply to a US university instead of a Korean one.)
Insane extremism - the country is socially divided between men and women. A lot of men in Korea DESPISE women, and feminism. This is because the early feminists in Korea were feminazis instead of promoters of equality. They would often talk misandry and essentially ruined the foundation for healthy social activism in regards to gender equality. As a result, there is a strong anti-woman mentality in Korea, and it really makes life for women hell. Another case of extremism is the Internet culture. A lot of people have been driven to suicide due to harassment online. And the Korean language really cuts into your soul, unlike English. This shit HURTS. Idk how to explain it but it's like a fucking dagger.
A famous Streamer called Jaemmi 잼미 committed suicide recently because of online harassment. Her mother was driven to suicide weeks/months prior due to the same kind of harassment.
"And then I lost my mother. I know I haven’t really talked about my mother’s death until now, but she took her own life… She, too, had been battling depression, caused by menopause. But after seeing me struggle, I think it [got worse]. I think she may have died because of me. I killed her. Had I not been a streamer, she would be alive…"

Korea has a serious dark side.
