The problem is the assumption of linearity. Things are good now but it seems to me things are getting better at a decelerating rate, and some trends have even started to reverse in the most westernized countries. Most of what’s getting better in the world is in places like Africa or Brazil, emerging economies. Things aren’t getting better for a lot of people in a lot of cities in America. People are fleeing la, sf, etc... Empires rise and fall, predictably.
