I'm not entirely sure this is a comprehensive reading of what Graeber wrote about La Conquista. (also, I would have to re-read the section to determine whether he characterised what he wrote about as genocide).

What I personally appreciated learning from that section of his Debt book (which I had not learned from any other historical source I had encountered up to that time) was the extent to which the actions of bankers enforcing claims upon their debtors *in Europe* radiated out to the effects - some of them quite ruinous - experienced by people as far away from Europe as Mexico.
