Slaves

Slaves are members of the poor strata of the population. A country will only have slaves if it allows slavery.

Slaves are (typically very unwilling) workers of RGOs. They provide a throughput bonus to the RGO they work on and don't earn any income from their work, leaving more money for the aristocrats.

Slaves never get to vote, even with a universal vote franchise, and they have no needs whatsoever; slave-owning nations will report every slave as receiving 100% of their "luxury needs."

Once a country has outlawed slavery, all slaves will be immediately freed and converted into farmers or labourers, depending on the RGO type they worked at.

Rebels
Slaves who become part of a rebel force will always join as irregulars.

Ideologies
Most slaves are interested in changing their society's political structure, so roughly 80% of slaves are liberals with the rest being mainly conservatives.

Policies
Slaves attach little to no importance to most political policies, since they gain nothing from them either way. However, about 30% of slaves considering gaining full citizenship their most important political issue.

Issues
The most important issue to about slaves is, of course, slavery. About 50% of slaves want to outlaw the institution but roughly 20% are actually content with their lot and want to see it remain.
