There is only one, only complex, that can be rephrased at will - and which was the intention of the coiner of the expression.
> I was unaware that he coined that term in French (when it may already have been coined differently in English before) [...] Is that where you got it from?
I know it from Books, the good old traditional way. And not necessarily books in French: it is in the works of Paul Johnson, for example. It was not "independently coined by many" - all authors I have state that Sauvy has coined the term.
> By the way, Sauvy "repudiated" his definition in 1989
Surely at some point he may have felt to retract, given that an expression coined to make a point and a good intellectual proposal - "what will be the future and the world role of those that we can now recognize as the non-aligned" - from analytical effort had become a synthetic vulgar twisted label. But the descent into vulgarity was not Sauvy's intention, and certainly there is no intent of attributing "superiority/inferiority" to the parts (as you will have seen from having read the piece on the Observateur).
So again: when somebody mentions Schrödinger's cat or Hegel's cows, you cannot assume that the context be violence or discrimination against animals "as mass interpretation became at some point". You cannot attribute to the speaker unproven intentions especially if dubious, especially if frequentistic. In general; as written, here it is explicitly forbidden.
For the rest, incidentally, I do agree with a tirade against the dire state of civilization in the decadent "western world", especially about the denunciation of «eunuch-like consumerist subservience» (50 years ago a conscious warning and today the token of the dead), but it was uncalled for from the post of flohofwoe.

I hope you are not falling into other assumptions.
