We are certain. American economic collapse is orders of magnitude worse than a recession or a trade war. Like starkillerfish said, the entire world's economy is geared to supply american consumers and industry with cheap goods. However that doesn't describe collapse in its entirety. If the US economy were to collapse it would take the world's financial system with it. It would be as if the entire world was placed under Russia style sanctions all at once, necessitating a rapid and complete overhaul of, well, everything. Only most of the world is nowhere near as self sufficient as Russia.
It's not so much that there's no alternative. Of course there is. Its just that none of them are easier than the status quo. Much is written about how a country like China wouldn't want to take over the financial system. In part because that means becoming the new US, the new exporter of junk cash and therefore the new importer of cheap goods and exporter of jobs. In part because Chinese capitalists have their assets priced in dollars. The point is that China is doing what it is currently doing while it has options. An American collapse robs everyone of options.
Making some assumptions about that Other vote, and also assuming the indigenous vote would still rather González over Noboa then maybe the center-left will win this time around?
