A dystopian society is unlikely to thaw out and revive people in cryostasis. Cryostasis revival makes sense for societies that are benevolent and have a lot of free resources. Also, be careful not to try to generalize from fictional examples. They are not evidence. That's all the more the case here because science fiction is in general a highly reactionary genre that even as it uses advance technology either warns about the perils or uses it as an excuse to hearken back to a more romantic era. For example look how many science fiction stories and universes have feudal systems of government.
