Look at much of post-colonial Africa today. Roads collapse and are never repaired. Copper is stripped out to make bracelets and the wiring is never replaced. Etc. I know that Africa is a rather special case, but it proves that declines can become self-reinforcing, even in our modern era.
Here’s a thought for you. What if the polls were showing dear leader had no chance of winning about the middle of October. Would anyone be surprised if he and Bill Ayers cooked up a scheme to set off a coordinated series of EMP’s across the country. The resulting chaos would make elections impossible so dear leader would be forced to maintain control. Remember Bill Ayers said it would be necessary to kill 25 million Americans. That would be easy for them to accomplish.
“even in our modern era.”
Every falling society thought they had a modern era that could only advance forward.
