Ping; and a very good question. I could speculate or guess, putting myself in the shoes of a would-be-depopulationist, that I wouldn’t want a total collapse of technology, because then my elite life wouldn’t be comfortable and fun. I would need enough competent people to make things run — which are the right-thinking people — but never a majority. Thus migration replacement of useless, overpaid leftists by menial, underpaid migrants. Preferably illegal so they can be forced to accept no economic mobility.
The other off-the-cuff thought would be that vaxx debilitation and death is only one arrow in the quiver. I find this one more likely given they’re pursuing mass starvation and intentional energy crises and war.
Neither are solid enough to stand on; only speculations, not even theories.
Lastly you caught me out with the by-line “BalckFemaleArmyColonel” ... thought you’d created an alter-ego for a short moment. :)
Typing too fast:)
