I say yes and no.
Yes - There slaves. It's not something you'd want being held against your will. Therefore it makes them a slave and doesn't allow them to have an opinion on the matter.
No - In the wasteland, what if one of those people using the virtual reality (not sure of the storyline, completed ages ago) have nothing left in the wasteland? What if there family were taken, lost or died? The dreaming and the virtual reality becomes there life as they have nothing to lose, as it's there in that virtual reality being lived. Something they might want rather than trying to rebuild knowing your loss is personal.
