I know of no theocracy in history that was not tied with the weather ruling class.
If true, it doesn't change what I said.
Moses and Aaron ruling is a theocracy.
However in theory wealthier will dominate unless it's not a factor in government.
But who will teach us to correctly apply rules, right now, rich control propaganda, education, system, etc.
The one to me is God. We cut off everyone but God and his chosen from authority guidance, and don't allow wealth to play a role in that, and we have a chance to come to the light and be enlightened in all our affairs and be a just world and race.
Remember, world needs a person like David, Solomon, etc. But when Solomon was given intense kingdom, powers, authority, miracles, domination, control, people became more disobedience and turned to sorcery and accused him of being a sorcerer.
So God provided perfect rulers and even gave a person so much signs and power and domination, but if people don't enjoin each other the truth, the falsehood regarding him (Sulaiman (a)) prevailed.
So society has to do it's part in a theocracy.
So far humanity has failed God, his revelations, and his chosen.
