These are all equal to: Those who have the most resource decide. What's the civilization part to differentiate it from any animal world?
It's hard to take this kind of comment seriously, but just in case, the answer to your question is: The prohibition on the use of force except in defense and the requirement that people honor their agreements.
As stated elsewhere. As the wealthy landowner it seems that I can get very similar results to things like oppression, apartheid, slavery - without initial force (in your specialized usage of the term). i.e. I can control wages and the kind of jobs (via contracts with businesses), I can control movement (via road contracts) and I can control where people live (via contracts for the land they lease) which bathrooms they use etc... Should these oppressed folk rebel, escape whatever...they will be hunted down and returned by your government (terms of the contract).
