These guys are literal slaveowners getting angry that they are being given a token punishment. This is not the time for sweet words, logic or anything remotely conciliatory. The stance they are objecting to is already too lenient. As far as I am concerned, everything they own is by rights the property of their former slaves, and they should be lucky the guillotine hasn't been invented yet, and that literacy is rare enough that we still have a use for them for the moment.
A bit of a protest vote, but what the hell.
[X] Plan Radical-ist Reconstruction
-[X] "You misunderstand. The policies I just put forward where already a compromise between justice and the necessity of maintaining a functioning society. Make no mistake here: everything you have gained from the men you claimed to own is by rights theirs and theirs alone. Your grand houses, fancy clothes and shining jewelry, your estates and all manner of business interests, and all the fine things that you and your fathers and theirs before them have built on the backs of slaves are not yours by right."
--[X] "I had been willing to set that aside for the moment because of the harm a complete breakdown of the social order would surely cause. After all, your slaves can not eat your fine silks. Peace, food and shelter for all must be the order of the day, and if undoing the full measure of wrong you have done must wait somewhat, then that is one of the unfortunate hard decisions that come with rulership."
--[X] "I had thought it would be worth keeping all of you around for the moment and in some semblance of your station because of the extent to which you have kept others ignorant of the skills and knowledge needed to replace you. Between people already in my employ and your most highly placed and clever underlings, I am sure I could make due, but it would be a bit more difficult and I have need for many of those resources elsewhere."
-[X] "You seem to be dead-set on convincing me I was too lenient, and that if I give you any power at all, you will foolishly and self-destructively try to use it to stand against me, and the changes I plan to make. I would still rather have the help of any among you with the sense to know when you are beaten and the adaptability to live in a different kind of society, but it occurs to me you could serve just as well and with less trouble as clerks and bureaucrats rather than masters and owners."
-[X] "In the days to come, I will make a full accounting of what is owned by those who owned slaves, and who it rightfully belongs to."
--[X] "I am not entirely heartless. At minimum, you will all be left with enough to re-establish yourselves and live humbly but comfortably enough, provided you are willing to work for a living. For those without any other honest skills, I am sure I will have many uses for those who know their letters and numbers."
--[X] "Anything you have come by honestly will of course be left to you, provided your assets cover your other debts and obligations."
-[X] "To ensure compliance, and that as little ill-gotten wealth as possible goes missing, each of you and all of your fellow perfumed brigands who are too terrified to leave their lairs will be put into house arrest until this is properly sorted out. I will not take kindly to resistance, subterfuge or attempts at escape."
-[X] "I don't really need you, I don't care what you think of me, you are entirely in the wrong morally and you have no real power beyond the wealth that will soon be returned to those who earned it. Swear your vengeance, yell until you are blue in the face, or break down crying. I care not. Your day is through. Be glad I allow you to linger. I am prepared to withdraw that kindness if need be."
-[X] "As for the minor cities, I assure you I have no particular need for them to join me willingly. Or do you think they will resist more effectively than Tyrosh did?"
