At this point in time, the NA LCS is one of the richest regions in the world along with China. They’ve tried to import the things that Koreans do, but could never get down the entire work ethic cultural thing that lets Koreans play inhumane hours at a time, nor do they have the strong hierarchical nature of their interpersonal relations.
At this point, I think they should be looking elsewhere. They should study LMS, EU, and China. All three other regions have been historically or recently better than their NA counterparts despite 2/3 of those regions having far fewer resources in comparison. What is it they are doing?
Or they can keep running the same experiment and see how that works out again.
