There appears to never have been any thought by the oligarchs that have brought us this fascism that it did not work. That giving absolute power to one person is a mistake even when that person isn't a deranged asshole to start with.
It didn't work for the rich people that wanted to protect their investments from the Socialists, and that is about exactly what is going on here, our rich were so scared of a little moderate reform that they created a monster they cannot control that will destroy them if they get what they want destroy them one way and or another.
They think they are in charge, that they will never run afoul of the supreme leader, that the supreme leader will not tank the economy in 12 different ways, and go ahunting oligarchs to seize their assets. All very mistaken and all going to happen sooner than later.
