And governments quite often abuse their citizens. But, with a personally-financed coup, there is a much shorter chain of command to go through to get results. If Coup Dictator A doesn't improve conditions quickly enough, then along comes Coup Dictator B to fire him and take over. This is what I mean by a democratization of the governance process. No elections to mess with, no pleading to one's representatives for change, etc. Simply remove A, install B, and get on with it.
Then oceans of blood would be an understatement?
