"According to “Star Trek,” everything we're worried about right now will be OK. There will be other things that go wrong — a species intent on taking over the universe, arguments between factions of aliens — but these concerns are foreign enough that they're intriguing rather than scary. The show depicts its fair share of pain and suffering, but usually it's the aliens who suffer in any permanent way; when humans do, it's an aberration from the new normal that's been created. By the time the Enterprise is exploring new worlds, we've eliminated climate change, war, disease, xenophobia and sexism. On Earth, everything is as it should be. In the rest of the universe, though, these things still exist, and nearly every conflict on the series involves starship crews becoming entangled with random and calculated unfairness, cruelty and moral complication. We get Klingon in-fighting, alien merchants selling slaves, a civilization about to be decimated by its dying star. “Star Trek: The Next Generation” is especially prone to depicting easily-recognizable versions of real quandaries. The characters encounter everything from sex trafficking to territorial disputes on distant planets, and they're forced to confront moral codes that exaggerate the ironies and falsehoods of our own beliefs. Familiar dramas play out: Apartheid is displaced onto a matriarchal society in “Angel One,” and the Israel-Palestine conflict plays out with a group of alien separatists in “The High Ground.” Here lies the ethical problem with “Star Trek,” and also the thing that is so deliciously attractive about it: Every earthly dilemma has been outsourced to an alien species, and we get to be the arbiters of goodness, the agents of scientific reason. Who wouldn't want to buy into this vision of the future?"
