Star Trek is SciFi Fantasy BS. The economies in Firefly are much more believable.
Speaking of SciFi fantasies, consider the original story on which The Day the Earth Stood Still movie was based (Farewell to the Master by Harry Bates), the surprise ending was the realization that the robot was the master, and the humans were the slaves. The movie changed that around for reasons of political correctness during the cold war years.
This is something to consider if Musk’s robots begin to take over.
