Why do Korean women's teams perform well with low income?

Korean kpop has had a complete entertainment system for so many years. Idol is recognized as a legitimate occupation in Korea, so many children have the will and dream to become idols since childhood. Of course, kpop is so popular that the competition must be fierce. Some children are trained in the company in primary school, and they have been practicing for seven or eight years before they can debut. Moreover, everyone's practice time is uncertain, and it takes opportunity and luck to debut. Therefore, during the internship, everyone worked hard to get a chance to debut, and everyone wanted to debut. However, whether you can succeed after your debut depends on people's luck. Some women's groups failed for three years, and finally ended in dissolution. So once you debut, everyone cherishes the opportunity to debut and will try their best to express themselves and make the group popular. There are very few cases where it is not implemented seriously. And the fortune of the Korean circle is hard to say. This year and next year may not be able to fire. Idols are equivalent to products, and there will be a new round after a round of launch. If you want everyone to remember you, you must work hard. For the problem of low income, each company gives artists a different share. 6.4 7.3 is mostly because the company draws more profits, and everyone in the portfolio basically shares the income, so the income is not much. If you want to make more money, you must show more and make yourself popular, which is equivalent to a way to gain benefits. The entertainment circle in the mainland is very strange. Artists obviously don't work hard, but the asking price is sky-high. I really hope that some artists can learn to do something with a dollar instead of working hard with a high salary.
