Most of the time, the main issue is not the lack of knowledge; rather it’s the lack of discipline to act on that knowledge. I’ve never think that Indonesia and many other developing countries are underdeveloped due to the lack of knowledge of proper policy; rather, I believe it’s because of the lack of good governance.
It’s as simple as thinking like our own affairs. A successful person is a discipline, ‘goodly governed’ person. We can’t expect someone to be a good artist, farmer, teacher, or merchant, without being discipline to their own. A developed country is the accumulation of a developed individual.
