Here’s an aspect of “global inequality” that is completely overlooked or considered taboo:
One dimension or axis of world history is the world-historical “land question”—which groups “grabbed” gigantic pieces of the land surface of the earth and which didn’t.
Thus: Canada, China, Russia, Brazil, America and India represent territorial “mega-grabs” which typically means “world heft” is in the hands of these big countries which are “monstrous” compared in size to the Andorras, Portugals, Liechensteins and Jamaicas of this world. This question of “who grabbed what” is not allowed in high school or college and is usually “swatted away” by phrases like “manifest destiny.”
A Putin can also invent his own regional “Monroe Doctrine” (i.e., stay out of my sphere of influence as randomly defined by me) and thus we have local (in this case, Russian) reinventions of America’s “Manifest Destiny” and the “Monroe Doctrine.”
This inchoate “relativism” at the heart of human affairs guarantees instability and mayhem and “historical inequality” (i.e., who gets to be “anarcho-lawless” and who doesn’t).
There can’t be a real education without putting on the table, in front of him or her, on their “educational plate” all of these truths, from the personal to the impersonal to the world historical.
