'Death cross': South Korea's demographic crisis marks a warning to the world

They're called the Sampo Generation: South Koreans in their 20s and 30s who have given up (po) three (sam) of life's conventional rites of passage -- dating, marrying and having children. They've made these choices because of economic constraints and in the process have worsened South Korea's demographic imbalances. Last year, when the country registered more deaths than births for the first time in recent history, then-Vice Finance Minister Kim Yong-beom pronounced the milestone a "death cross." "I Live Alone" is one of South Korea's most popular reality TV shows. It follows the single lives of movie actors and K-pop singers engaging in mundane activities such as feeding their pets or eating ramen in the middle of the night -- all alone.
