Very good question, I will answer according to the following rule: "He who does not know everything, do not let the whole". We accept the democracy we have, not trying to copy it, because we have our own life…  According to the question, I prefer that the change must be only done by a governor, who has a clear vision. Not through people who are easily diverted from their requirements, because when they form manifestations or crowds, the collective mind is quickly affected, loses its balance and tends toward chaos.
