These days, due to Corona, the economy is in a difficult situation, so our society is in polarization. Moreover, the self-employed is on the verge of going bankrupt. I am sad about that. When i was young, I had difficulty. So, I can understand them. In the post-Corona era, what is a better life? When I was younger, I wanted to live a stable life. Probably, everyone will want to live a simple life. We should take into consideration ordinary people's life. Owing to Corona, on-line companies are making fortune. Recently , according to a YTN news report, the Kakao company announced that its sales had amounted to up to 4 trillion won. Naver, Nexon, Coupang and many major banks, to name a few, have recorded increase in their sales as well. On the contrary, unluckily the self-employed and small enterprises are going broke now. There is no sign of respite in their crisis.
