What sci-fi gets wrong about income inequality

I wanted to love Bong Joon-ho’s Snowpiercer. I really did.

All indications were that Bong’s science-fiction epic would be a visually stunning parable about out-of-control economic inequality fused to a kick-ass action movie. That’s just the kind of science fiction we need for our post-Occupy moment. Unfortunately, though the film is indeed visually ingenious, its final act both figuratively and literally goes off the rails. Even worse, the movie fails in more or less the same way as every other recent work of popular science fiction concerned with income inequality.
