Oh My ! What a beautiful statement that is, thank you for sharing the link !
With 15 years in remote Indonesia I can witness that the changes brought after Jokowi's first election are extremely significant, be it in terms of infrastructures (OK we were starting from very low) or drastic reduction of corruption.
I can't see how to push the country farther without a decent education, it is mentioned in the article. But here again we are starting from very low level, 5 years won't be enough for the job. Jokowi referred apparently to inefficient civil servants. So let's take this as an example. When a new law is being implemented, it is declined from Central Government offices to Provincial then Regional offices who in turn, organise what they call "sosialisasi" meetings with the different bodies concerned by the new law, in order to explain the main aspects of it. Well, I can witness that last time I attended, none of the agents had actually read the law. They have been explained themselves by their hierarchy, but never take notes so remember as best they can for the restitution. That's a true drama in Indonesia : people don't read, and are not encouraged to. If you wish to understand what the law says exactly there's only one solution : read it by yourself !
So yes : eduction, education, and education. And it also replies to your second question. I may be wrong, but I think you can ask educated people to fight intolerance, whereas uneducated people will prefer to stick to their beliefs and will tend to embrace whichever statement, fake or true, that goes in the sense of their beliefs. It was particularly noticeable during the last elections : the speed at which the most ridiculous fakes were shared and commented positively was impressive.
Nothing is easier than influence a person who has no tool to sort the true from the false.
