$Direxion Daily Korea Bull 3x Shares ETF(KORU.US) This summer, a Korean girl texted me today saying this is the best summer she's had since becoming an adult. This year, she found a job and threw all her salary into the stock market, earning five years' worth of salary. Air tickets are discounted everywhere, and flying to an island for a swim only requires saving up a week's salary. The day before yesterday, while walking in Seoul, suddenly everyone on the street stopped what they were doing, hugged each other, and cheered. She said she was very happy, feeling a kind of illusion of a human golden age.
