It's not just Korean experts predicting that BTS has an incredible impact on Korea's economy.
CNN published an article titled "'Why the past decade saw the rise and rise of East Asian pop culture', and in it, predicted that by 2023, BTS would have an impact of 56.16 trillion KRW (48 billion USD) on Korea's economy. The predicted outcome is, of course, not just from album sales and concert revenue, but also from all the tourism that would come into play from BTS.
What an amazing number!
Okay, this isn't even about fan wars or some petty money. This is 48 BILLION DOLLARS! People, BTS does really have an impact around the world. The way that Korea went from being one of the poorest countries in the mid to late 1900's to now being very very rich and powerful is insane.
