Heck, Star Wars is the very embodiment of the "science and technology = evil, back-to-nature traditionalism = good" mentality. All the Imperial stuff is bright and clean and gleaming and high-tech, and it's the noble Rebels who are using run-down ships and equipment and spiritual forces and antique weapons and bows and arrows and log traps and such.
Good point. There's also the crucial moment where Luke switches off the targeting computer and trusts the Force instead . . . .
On the other hand, the tone
of Star Wars owes much more to Edgar Rice Burroughs and Flash Gordon than cautionary tales like THX-1138 or Soylent Green.
