The primitive probably has socialist plumbing.
There was a time during the Brezhnev era (1964-1982) in the Soviet Union that the socialists boasted that "98.5%" of all homes in the Soviet Union had indoor plumbing.
That was correct, but then and again, it wasn't correct.
When I was wandering around the socialist paradises of the workers and peasants during the mid-1990s, I was intrigued that so many peasant cottages had indoor plumbing--the bathtub, the sink, the commode--and doubly intrigued that no one used them, instead always going to that little shack in the back.
The peasants put potatoes in the bathtub, onions in the sink, beets in the bowl of the commode, and hung herbs and spices to dry in the tank of the commode.
I learned that there had been much resentment about this indoor plumbing. Peasant cottages are very tiny, and the socialists made them even more cramped, by stealing one part of each cottage so as to install this indoor plumbing.
And then after all was installed, the socialists forgot to put in water and sewer lines leading to the indoor plumbing. Such indoor plumbing wasn't being used for the intended purpose, because it couldn't be used for the intended purpose.
No water incoming, no way for water to outgo.
Ah, how wonderful life, under socialism with free medical care for all!
