Being clear both Intergenerational taxation and White Genocide theory are both a type of Reproduction Anxiety politics. They share common groudwork in this case as do a lot of similar discourses under this umbrella. The more encompassing and existential one right now is that there is NO birth rate replacement happening in nearly any country right now much less globally. People straight up aren't fucking for kids any more and thats new.
I don't consider myself Malthusian because of the whole considering myself a marxist thing. That said, I think the concept of 'birth obligatory' politics is disturbing and wretched in form. With that said this is not a 'clean' stance that you can take because when you refuse the idea of these obligations on a mass level you are basically setting up for waning vassal state countries fading out and emmigrating into their host countries. On the other hand, the main way you tamper for birthrates is to stop giving people contraceptives and reaffirm heteronormative family models. I really just dont think people in the agency of the lives they are currently living owe their national economies fucking anything and its horrific to think like that. More notably, and perhaps in more firm adjacency to Marx here possibly (in the sense of noting real historical changes since he was writing), I think parenthood produces are reaffirms a false conciousness, if not has the conditions in itself to excuse bourgosie and lumpen behaviour patterns. This is unfortunately just a scrap thought and so I have no way to wrap it up in any conclusive direction

but it's just been one of those subjects thats been on my mind recent.
