I'm so glad this is getting some attention. It is an amazing system and while a bunch of issues like people leaving etc are pointed out, for the most part "what goes around comes around" but in a very positive way for the nation.

People feeling free to travel and experiment, while being educated, just means eventually when they return home they bring a lot back with them. You wonder why a nation in the middle of nowhere can thrive? Well yes there is a mining boom, but also the country is well equip enough to make the most of it.
