My today's philosophical thought:
Morality is a plea to be oppressed fairly, and not excessively.
Dominants have little use for morality, except that a society with fair oppression is more stable against degradation, revolution, civil war, and sabotage.
(All societies are dominance hierarchies, and oppression is a structural feature of any dominance hierarchy.)
