Piggybacking on what Veik said, we don't necessarily consider most countries today to be slave states, but slavery is very heavily dependent on definition. There are a lot of gold and diamond miners risking their lives in Africa under paramilitary rule just to make enough money to feed their families, which isn't necessarily slavery because they are getting paid. The example of Chinese industrial workers is another good example; they're being compensated but how much choice they have in where they go and what they do is debatable. You could almost wonder whether capitalistic societies really are that different from slavery, since I know a lot of my European friends are appalled at the scant benefits we get in America. I just have to tell them that it's how it is, nobody really goes above and beyond on benefits to keep costs down, so you can't really change jobs for benefits easily. Some of them call that slavery.
It's just one of those things that pops up when you say that a society doesn't practice slavery. There's an AWFUL lot of grey area, especially with disenfranchised people. Does it count as slavery if they're dissociated? Is it not slavery, but there's no minimum wage and thus you can exploit them without calling a spade a spade? Do they even have a choice, considering they need to probably take the most dangerous and terrible work possible if they don't want to go into illegal activities?
I mean, even at 10% of the population, we'd be talking about, over the entirety of Caldari space, an absolutely VAST source of cheap labor that has nowhere to turn to and, from what I've heard, no real human rights. That was why, in response to Kunarian's point, I said they were like illegal immigrants more than regular disenfranchised people. If you're disenfranchise, the government still wants to know where you go if you're disappeared into a swamp. But if you're off the register, you're a deniable asset. You could vanish and, considering your illegal status, you might simply never be heard from again.
Maybe they're just a bit more like the SINless.
In any case, transportation probably isn't too much of an issue. In Houston, there were little back-lot pockets where laborers would gather. People would drive up, pick them up for a day's work, then drop them back off again. I always thought that was strange, but in a lot of developing countries that's just how work usually gets picked up. You're a contractor at the mercy of fate.
Not sure if that's what the Disassociated are, I'm just providing some examples. I think it's worth noting that nothing in EVE is born out of a vacuum, since there aren't many particularly alien concepts floating around. Nothing may match up 100%, but it's not like EVE has a government run entirely by lottery.
Although come to think of it, there was a civilization that tried that, too.
