id argue there is a difference. i know im wrong though and there are many types of slavery. the reason i choose to make a difference between them is because ive seen both and i cannot to this day process what i saw, and the attitude of people. a slave from my experience is seen as subhuman. and when religion is used to justify it, its to me different from china. but i mean chinese citizens cannot leave their country and start a new life somewere else. so i think in the context of china you might be even further correct.
