I agree that, stated outright, it can sound paranoid and conspiratorial. But think of it as a mindset: “if the poors die that’s because they deserve it, for not being as smart/tough/clever/strong as us”, along with background assumptions about white racial superiority and needing to counter a “great replacement” of whites. Looked at that way, as implicit at least in their outlook if not consciously held, it doesn’t seem so implausible that this is influencing their policy decisions.
