We are demonstrating the ability to learn from history, something DNC leadership lacks.
(also highlighting precisely how bad a global trade collapse would be)
It also ties into the Dem's wishing furiously and in some ways trying to make a recession or a depression happen in order to hurt Trump and/or his supporters. Short sighted shit like that has massive repercussions and the people who Hate Double Plus Ungood Orange Man don't really look at the fact that when the US drunkenly stumbles slightly other nations end up flat on their face with the universe taking the boots to them.
People like MovieBob and people like him want the Midwest to collapse, people to lose their farms and livelihood, while some groups want everyone to eat bugs.
Now, apply that to nations that rely on US farming to have cheap food, that rely on cheap US oil exports suddenly not getting their food because farmers have had to either shift to cash crops/crash herds or have gone bankrupt. You see some of that right now in California with the drought going on that's exacerbated by almond and other high water requirement crops.
Add in the problems with Africa killing their farmers or otherwise fucking up their local farming.
The Great Bronze Age Collapse is a good example of how shit can QUICKLY go downhill for large populations.
The Ethopian Famine that I saw commercials of fly covered African kids with some rich white chick begging me to send money to them wasn't that long ago and the world sent a LOT of aid to them (what happened to that aid is another fun thing that we probably shouldn't get into here) from money to food to tractors to fertilizer.
A recession or, worse yet, a replay of the Great Depression would basically fuck the world ala the GBAC. The world during the Late Bronze Age was just as complex and wide-reaching as today's world, and, as we saw, just as fragile as it is today.
(Sorry, I'll quit sperging about it and how it applies to current events, I've just fascinated by it since I first learned about it)
