Interesting article, and one I am sympathetic to, but the inclusion of "Western" (and democratic, to a lesser extent) alongside educated, industrialized, and rich when transitioning from talking about a "lack of sanitation" to "adequate sewage disposal" was kinda... jarring?

Other cultures may not have the same type of porcelain thrones we use, but I think the EIR parts still have effective plumbing, even without being WD. Or do they just not have any of the same issues and pressures around public toilets?
