Howe is the economy of south korea different from that north korea?

North Korea is a communist country run by the Communist party. South Korea is run by Capitalism and is a democracy. South Korea is where all the cool Korean products come from like Hyndai cars, Samsung and LG phones and stuff like that. Also when you hear that Korea's and Japan's high school students are doing the best, the news is refering to south Korea.Yeah Democracy rules!
