I was thinking the justice system, but yes the entire concept of government and law is built upon the monopoly of violence. Bringing it into this discussion is reductio ad absurdum. Even property rights are protected by the same monopoly (and even more directly).

My point is that the so called "social contract" has never been upheld by large corporations - it may have seemed that way at times but it was mostly self serving marketing, not anything that would influence their treatment of employees vs their shareholders and executives.

Furthermore I'm arguing that we shouldn't rely on them to uphold it. If we have a belief in what is universally fair or just (i.e minimum wages, no child labor, no slavery), we should encode it in law, not hope corporations find their conscience to renew the social contract.
