I think there are many variables and as an experiment, it is probably a success. I am all for self-voting if you have the power, but they should have stopped and thought for a moment on efficient ways to counter abuse of power, you cannot say that people will govern themselves, I sincerely feel that humans are not a species capable of this without there being some source of fear that no matter their power they will fear the wrath of.
Probably why all justice systems are such a shit show but that is beside the point. People who abuse power are no better than a mob who demand without compromise, they all feel they are owed, I like to call it poor mans mentality.
