I would say that the question itself is badly formed at best, because the data that is being shown comes from teenagers who fit into a particular group who are working to get a grade and meet or exceed the expectations placed on them by an external source. Ideally, government would work to get a passing grade and to meet expectations placed on them by an external source (the commonwealth of the people), so of course they are going to look better than whatever mishmash we currently have. That overlooks, though, the simple truth that should we transition to a teenager lead world that we would be removing those two restrictions and therefore logically we would be creating a government of tyrants whose limited tenure (since they must be teenagers) would inspire them to actions of unimaginable selfishness to meet their immediate desires. Sure, it might go well for a while, but such a system would be so fragile and so corruptible that when it went down we would long for the music of Nero's fiddle to comfort us.
