Come on, Drew, you are making this way too complicated. Life runs on a kiife's edge. A little bad luck, like the election of moronic crazy man to the top ledership post would knock any nation into the dumpster.
Even "advanced" nations possess a big slice of the population that reacrs almost exclusively on perception. This gives conmen like Trump an opening to wreck a country.
In the case of Trump's election it required a host of bizarre events to elect him--so now we pay an enormous price. Shit can happen to any nation. Let's just hope it 's not as bad as Germany 1933 to 1945.
