Why all types of government stink

All governments stink almost as badly as anarchy.
Why? Simply put, it's because of greed.

Democracies quickly degenerate into oligarchies due to people realizing they can vote themselves a larger slice of money and power. Simply put, the majority can destroy the rights of the minorities over and over again until there is the cleverest minority with absolute power. Also, a pure democracy (where all decisions are voted on) can never function quickly, but is bogged down by bureaucracy (due to any six people having seven different strongly held and mutually exclusive ways to solve the problem) until a representative is voted decision making power (thus effectively killing the direct democracy in favor of either a representative democracy or a dictatorship). Examples of this include Rome and Star Wars. Constitutions and division of power last only as long as the elected officials respect the rule of law and the people hold their representatives' feet to the fire.

Monarchies, dictatorships, and oligarchies work well as long as the leaders respect a higher authority than themselves. They can also be held in check by fear of their people revolting, but this is normally dealt with by picking the least favorite group and attacking them until they are not a threat, then repeating the cycle until everyone is repressed. Once a ruler or group of rulers neither respect a higher authority nor fear their people, all decisions are made based on their own best interests.

A theocracy would be extremely tempting if you believe the religion that is in control, but is still corrupted by our sin nature of greed and pride. This time, it's mostly pride, due to the leaders thinking they have a monopoly on Divine revelation and thus find any question of dogma to be a personal affront to their divinely appointed leadership. As a Christian, I find this to be the most tempting and the most terrifying system. It is tempting to me because we have a constitution readily available (I would only use the ten commandments and selected sections of Mosaic Law dealing with the behavior of the rulers-particularly the ones ignored by the Israelite kings) I find this more scary than any other due to our sin nature that will quickly cause the human leadership to add their own interpretations to grey areas and then declare them to be inspired truth. The only way to keep a theocracy good is continual intense fear of God's imminent supernatural smiting for even minor misapplications and mistranslations of His commands.
As Darth Vader said: "Do not want"

In case I didn't make it clear earlier, Anarchy is even worse than these due to there being no rule of law to protect you from me and me from you. Without law, all we have is mob rule, and the only thing worse than one stupid person is a whole bunch of stupid people (and the stupidest are the people who think they're smart).

What do we have left? probably just a revolution every 150 years
