Although I can really sympathize with your sentiment, I disagree in some parts since some ideas mentioned may prove to be a bringer of more problems than solutions (no offense). Also, let us say that the good ideas are absorbed in the government system (in electing officials), there will always be a way for the corrupt and the influencial people that wants control over high positioned officials to have their way. This is because no single person is without a weakness that cannot be taken advantage of. Thus, the reason why even after all these years, the corrupt has never been erased on the most important positions in the human civilization.
