Hubris and greed may be related....It is a term I define [as]: "arrogant pride". Mostly associated with the Greek Tragedy "Oedipus". The conotation of "hubris" is that it ultimately leads to the downfall of he [who] holds the trait.
Greed is associated with hubris in this way: a man seeks sinister means for profit because he presumes he is so great he deserves that profit.
This concept is promoted by the "sheep" who believe that those with money and power have obtained them by some Divine Right of God and have more wisdom. Whole civilizatons have risen and fallen with this cycle.
