This actually isn’t a clear cut rhetorical question as it seems. South Korea has a massive dark side to it.
North Korea benefits:
-live life simply and freely like it was the 1950s
-gender equality is better in North Korea. Women can serve in the army for example
-You don’t have to study 16 hours a day or live your life as a robot to get into a SKY school and work for Samsung only to suicide when you are forced to retire early or get alcohol poisoning from all those 회식
-You aren’t under pressure to wear makeup or do plastic surgery
-You care about the survival of your family and friends as it is a top priority and there’s no materialism or superficial-ness in society
-free shelter, education and healthcare
South Korea benefits:
-No risk of execution by the state – although you are at risk of executing yourself (suicide)
-You can watch Kpop and Kdramas
-You *can* get rich though in practice it is extremely difficult to get rich in South Korea
-2nd most prostitutes per capita in the world, motels and nightclubs everywhere. nightlife is unparalleled.
-electricity, internet, food etc is plentiful and fast
I dunno.. you decide which Korea is Best Korea
