"Be the change yo want to see", I guess. So, my pet peeve theory is that "the rule of law" is not something the ruling class needs to cover their track; it's something the ruled class needs to cover their shame. Shame of being ruled, but also terror of being ultimately subjected to arbitrary power.
For instance, I believe that in the feodal past lay people used to genuinely believe that kings got their authority from God; not because kings were good observants of the precepts of religion (they were not), but because that protects the self-esteem and helps hide the facts that their life was dependant of the whimsical violence of the princes.
I find it surprisingly hard to try to convince myself that there is no such thing as "rule of law", that for instance the overthrown of a non-aligned regime could be just about the oil and competition with China, although I know that's how future historians will deal with that non-story; There is some surprising amount of resistance from within to this idea. It's interresting to do the experiment.
Have you read Thucydides, "The Melian Dialogue"? Or Zweig, „Schachnovelle“?
