You and I think that because we have been ingrained to think that. Saddam Hussein would disagree -- as would everybody who thinks they could be a Saddam. They would think the most desirable government is them ruling and us as slaves.
Now, we're right and Hussein, Stalin et al were/are wrong. But our understanding didn't occur by random chance in a vacuum.
Our nation is founded -- with premeditation on Christ's teachings.
Franklin and Jefferson -- who didn't believe in the Lord's divinity -- wanted his teachings established. Adams, Washington, Alexander Hamilton and Patrick Henry (should he be pinged?) were fairly traditional Christians and weren't going to disagree.
And because you and I are Americans guided by Christian values -- whether we believe that Jesus is God or not -- we think that our goal should be to have a "stable society where the happiness of as many people as possible is as high as possible."
So it really seems that everyone tries to use the teachings of Christ (or any other god, prophet, etc.) to justify whatever he thinks is right.
