And I don't think that the white slavery discussion is particularly useful. It is too modern a paradigm. Roman slave practices always strike me as the closest clear model for Amarrian ones.
The PF seems to dither back and fourth on whether slavery in the Empire more closely resembles Roman stuff or 1800s chattel slavery, in my experience. While it's more styled that way in the surface (Slavery as a form of criminal punishment, annexing new territories for stock, etc) Roman slaves, especially post-republic, had a surprising amount of rights - They were protected under the law from murder and serious assault, had the right to their own wealth (to an extent) and to to eventually buy their freedom, and even to go to court to protest against their masters if they felt they were being mistreated. Later on, their owners were not even permitted to imprison them privately, and many punishments were completely banned.
Amarrian slavery doesn't really have any of that - Most of the PF describes Holders as functionally being able to do whatever they want, and control every aspect of their slaves lives. And of course there's a very strong racial overtone to it all as well as a cultural one concerning the "it is their rightful place" justification, something that the romans never had at all.
Well, I think like much of EVE, it's quite open to interpretation. I tend to think of Roman slavery as 'institutionalized', progressing over a long period of time. It would also be essential to award the slaves with
some rights, since the danger of slave revolts was very real and ever present. This was what happened in the Star Trek episode where they had a 20th century Roman empire. Slaves had labor unions, health care, dental plans and so forth.
There were periods in the Roman empire when slaves were so cheap that their owners simply didn't feed them. It was more 'cost effective' to simply work them and starve them to death. Slaves that worked in the mines, or on the farmer's fields were still treated quite harshly.
I think a lot of people also associate EVE slavery with Antediluvian slavery in the United States as well. The game developers certainly did a lot to contribute to that, by making all of the Minmatar dark skinned, and all the Amarrians as pale skinned. Apparently the idea behind the Amarr and Minmatar enslavement (as well as the religious angle) came from Columbus and his enslavement and extermination of the Arawak people.
Antediluvian was most certainly harsh and brutal, with Africans being kidnapped (as the Minmatar were) and forced into mainly agrarian labor. Like Rome, slave revolt was also a constant concern, which meant that the Americans had to maintain a Spartan like society with well armed men to quickly suppress any slave revolts.
I should mention though, that Africans weren't the
only slaves in Georgian America. Irish were transported as indentured servants, debt slaves that were considered as property until they were too old to be useful anymore. The Irish were easier to control, since they had a debt to pay off. The Africans would always be slaves in the southern states merely because of their skin color.
In EVE terms, the Irish might be comparable to the Ni-Kunni. They were slaves that became fully integrated with the dominant culture.
The Amarrian empire spans thousands of planets, and is divided between holders (the only legal slave owners) with 'patchwork' territories under their control. A slave in the Kor-Azor region may have a very different life than a slave in the Ardishapur holdings, based largely upon the whims of the holders.
Also, I think that urban slaves would be treated better than rural slaves, skilled slaves would have negotiating power, 'pet' slaves would be treated as well as a domestic dog or cat, unruly and rebellious slaves would be consigned to miserable, hazardous work, and so on.
