Here is one of those gems - especially appropriate for the Doubters and Scoffers.
In 2010, 8.5 million tourists visited Syria, accounting for 14% of their entire GDP. Eight years later, they have almost half a million dead citizens, and ten million more displaced into Europe. They didn’t see this coming, because if they did, they would have fled sooner. Nobody notices the signs of impending doom unless they’re looking carefully.
Further, the elites of a nation rarely take it on the chin. They can hop on a plane. The poor, disenfranchised, and defenseless experience the preponderance of the suffering, violence, and death. They’re the ones that should be worried.
Pretend you’re someone with your eyes on the horizon. What would you be looking for, exactly? Increasing partisanship. Civil disorder. Coup rhetoric. A widening wealth gap. A further entrenching oligarchy. Dysfunctional governance. The rise of violent extremist ideologies such as Nazism and Communism. Violent street protests. People marching with masks and dressing like the Italian Blackshirts. Attempts at large scale political assassination. Any one of those might not necessarily be the canary in the coal mine, but all of them in aggregate might be alarming to someone with their eyes on the horizon. Someone with disproportionate faith in the state is naturally inclined to disregard these sorts of events as a cognitive bias, while someone with little faith in the state might take these signs to mean they should buy a few more boxes of ammunition.
