Just because two things are called the same thing doesn't mean they're equal. For example, a Lamborgini Aventador is very different from a Toyota Prius, but they're both called cars. According to your logic, they would be the same exact things, because cars are cars, which doesn't make sense at all. Different things are different.
Of course different things are different. But both forms of slavery are still wrong, whether one be slightly more so or slightly less so. Whether it is a supposedly 'higher' and 'more noble' Imperial form of slavery, or just 'regular' 'old-school' slavery, they are both slavery, and they are both wrong. The rest is semantics.
Also, you need to ask yourself why something is immoral before claiming it is. You see, slavery is not considered immoral just because it's slavery. It is immoral because most slaves are born into slavery, and never had a chance to escape it. Slaves are usually treated very badly, and live a harsh life, without being able to change anything to it. But imperial slaves are not born as slaves, they are very well treated, and becoming a slave is always a result of their own actions. In a way, you could even call them "working inmates". Personally, if I was to be put in jail, i'd prefer paying my debt to society by working my ass off while living a better life than any prisoner who's rotting in a cell.
Did you read my original post? Slavery is immoral PRECISELY because it IS slavery, because it directly impinges on a prime, immutable right, one that NO ONE has the right to deny you, not even yourself. That most slaves are born into it, that they are treated harshly, etc., makes it all that much worse, and gives further evidence of how evil slavery is, but it is irrelevant to the argument I am making, in the end. If they are truly 'working inmates', this is a different story. I still bristle at the thought of a 'debtor's prison', but it is different. But they are called Imperial
slaves in the ED universe, and I would imagine there's a good reason for that. I would love to know why, personally.
The only thing that truly defines your rights, is the law. If the law say you don't have the right to freedom, then you just don't. Just like someone who's in prison, you can loose your right to freedom if you're not bright enough to use it right!
Whose law? If it is another man's, I really hope you don't actually believe this IRL, because it really is disturbingly wrong on so many levels. Tell me, who are the masterful arbiters of righteousness who decides what my basic rights are, hmmm? Is it you? Who? We are born with certain rights, they are inherent in our humanity, in our condition as human beings, and thus no man can trample on them righteously. If you hold to the idea that man's basic rights are legislated by his fellow man, than you better hope you're the one making them!
Going to prison for committing a legitimate crime is different. But there is a huge difference between picking someone's pocket or breaking their bones, and going bankrupt due to poor financial decisions. I know I'm no financial genius, so the thought of a few honest financial mistakes landing me in servile bondage is pretty terrifying.
