You write in the future tense, but I think that this is already happening. Fewer millenials are having children than previous generations, and those that are have fewer children.
I think the main driver is that most millenials simply can’t afford children, and this is a direct result of policies pushed by “those who have the ultimate power”.
Or maybe the millennials themselves see humans as unefficient meat sacks who might as well just pass the time with video games rather than striving.
Or maybe people actually think every child is precious, and those who have the ultimate power benevolently used their power to require every child get the resources it deserves, even though we can't afford it.
