I've said it before, but I'll say it again. IMO the present world order is built by and for the benefit of the rich. IMO it's unsustainable, because it depends entirely on exporting jobs to the most exploitable nations, and it needs ever increasing growth, like one of those pyramid scams, to keep the money coming in. Neither is indefinitely sustainable, and it was going to fall down eventually.
Whether it was going to happen now or later is irrelevant.
I doubt Trump is the cause of the collapse, though he may have hastened it by a few years
My generation had the best of it, but once the world population exceeded 5 billion, IMO it was heading inexorably to doom.
You just can't have half the planet's population attempting to move to the rich countries and that system survive.
and that's not even mentioning the destruction of the environment, which may result in water wars and widespread famine. What happens when the water from the Himalayas dries up, leaving over 1 billion people without water?
