>It's not so simple as 'developed world' vs 'developing world'

Of course. These are just useful categories. Humans like to put things into categories so we can make statements about ideas. Saying it's "not so simple" is a strawman as I don't think anyone is claiming that a country is a data structure with the capacity of 1 bit (developed or developing).

Maybe if you said or quoted something about how the act of using this categorical construction in analysis when performed too often is the physical cause of some sort of injustice.
