The problem is not that lack of examples. Technically, all two hundred something countries could take example of the best one in every metric and just copy most of the stuff to make life better.

The problem is that politicians are afraid to do anything (outside of direct and indirect enrichment). No one can blame some John Doe, chief Busybody of the Busyarea, if he won't do something. Because that didn't happen, nothing to point finger at directly, except for "you don't do enough", which is generic enough to be used at anyone and so ineffective at everyone. But if he will do something and it is immediately painful to at at least some group, then he will be blamed and his opponent will do that with pleasure too.
