Note that the criticisms of finance made by Pen could fit neatly into an anti-Wall Street polemic. I never liked the focus on Wall Street within Occupy, attacks on finance have traditionally been made more by the Right than the Left, and have to do with the dog whistle anti-semitism that long held sway in Europe.
The problem is capitalism and how it functions, not one aspect of capitalism. In fascism, it is the finance sector that is nationalized ('national socialism') so that ruling class factions in other sectors can hold more sway. In Nazi Germany this meant the BMW's, Mercedes' and Bayer's.
