From TFA: But for many South Koreans, the homegrown Netflix series is not just riveting entertainment. Behind the violence and horror, it has captured long-held anxieties and brought them to life on screen. It has also sparked a debate in South Korea about the exploding personal debt and widening inequality consuming this nation.
"many South Koreans" might include the creators but I would prefer if they could find a tweet or a Korean interview with the creators to actually be sure.
