Great science fiction occurs when the skilled writer creates a plausible universe simultaneously exotic and alien, while still politically and philosophically relevant to our world and our society. Great science fiction uses fantasy to comment about reality. –Blogger “Reappropriate”
The 2014 blockbuster Interstellar depicts a mid-21st-century USA that has undergone serious decline, in almost all areas, for decades. The USA still hobbles along but has turned into a mushy, faded carbon copy of its former self. Mired in hopelessness, the political apparatus is tasked with managing further decline (which it does in certain pathetic and entertaining ways).
After being shown this vision of our own future, at some point after about the first hour a different movie (in effect) begins. It involves the movie’s titular “interstellar” colonization effort and off we go “through the looking glass” into the wild black yonder of outer space. The rest of the film is only loosely related to the movie we’d seen up to that point.
Staying with the USA as depicted in the film’s first hour: What caused such a steep decline? The answer: “Blight” did it. Blight is only offhandedly-alluded-to on screen and is not explained. So what might it mean? Global warming? Not likely (see point #8 below). It will be shown below that “Blight” in Interstellar can be seen as a racial metaphor for the effects of the ethnocultural displacement of the USA’s core White population by immigrants and resultant Third Worldization.
(Preliminary Note 1: On spoilers; Once the major spoilers approach below, you will be warned.)
(Preliminary Note 2: We only see the USA’s Midwest in the movie. There is nothing necessarily USA-centric about Blight as a racial metaphor. It holds for other European-derived societies that are being subject to mass Nonwhite immigration (and, in theory, it can hold for any society at all undergoing such a process]. For simplicity, though, I will limit this analysis to the USA, the setting of the film).
