In my experience, enhancing national prestige is the job of large corporations

It has nothing to do with playing ball.
You have to be at the level of winning the World Cup..
Then it would be worth talking about enhancing national prestige.
Samsung is doing almost all the work for Korea's national prestige,
followed by Hyundai/Kia. Then maybe LG?
Aside from corporations, it's just K-pop singers.
