A few thoughts on what conspiratorial materialism might look like...
From quantity to quality: from one dead banker to ten thousand dead bankers.
From paranoia as individual pathology to paranoia as the correct affect and understanding of a pathological systemic order: from the false certainty of misrepresenting how the world works to the dead-on certainty of that misrepresentation as the actual presentation of the world's workings.
The problem isn't just the difficulty of cognitive mapping but what you see when you do it correctly. All those slippery connections, backhanded deals, flows of money maybe secret but never fully surprising aren't proof of hidden drivers at the wheelor cabals of the powerful pulling the strings. It's just the clearly lit fact of the totality, and hence mapping it better reveals only the tangles piled high.
And then to avoid the dysphoric muteness that results from the necessary attempt to present the mess sharply. Maybe to remember how Alexander the Great dealt with the Gordian knot (that is to say, sharply: don't untangle, just cut through) and learn how to do it en masse.
