South Korea's continuing dominance in archery is amazing but, like the effect of monopoly on economy, I think overdominance is starting to hurt international archery competitions.

IMHO, countries overdominating a field of sports should share it's knowhows and training programs with rest of the world, particularly with those countries that never had a chance to win an olympic medal.  For example, South Korean archery association should offer archery scholarships for amateur archers from third-world countries.  I am sure Korean companies like Samsung and LG will be glad to sponsor such scholarship programs.

Imagine the joy everyone will feel when those athletes win their countries' first olympic medal.  I also think such programs are far more rewarding than traditional international aids and foreign relation efforts.
