I'm going to explain the Donald Trump phenomenon in three movies. And then some text.
There's this universal shorthand that epic adventure movies use to tell the good guys from the bad. The good guys are simple folk from the countryside ...
... while the bad guys are decadent assholes who live in the city and wear stupid clothes:
In Star Wars, Luke is a farm boy ...
... while the bad guys live in a shiny space station:
In Braveheart, the main character (Dennis Braveheart) is a simple farmer ...
... and the dastardly Prince Shithead lives in a luxurious castle and wears fancy, foppish clothes:
The theme expresses itself in several ways -- primitive vs. advanced, tough vs. delicate, masculine vs. feminine, poor vs. rich, pure vs. decadent, traditional vs. weird. All of it is code for rural vs. urban. That tense divide between the two doesn't exist because of these movies, obviously. These movies used it as shorthand because the divide already existed.
We country folk are programmed to hate the prissy elites. That brings us to Trump.
