** spoiler alert ** brief notes for myself:

happiness, two kinds (neg/pos) pleasure seeking, pain avoiding.
societies/people are unhappy b/c of guilt. religion plays a part, is an illusion
ego feels guilt b/c of superego (conscience) or authority outside self (when gets caught being "bad")

labido->happiness->stolen happiness/cock blocked->guilt->aggression

Communism: limited outlet for aggression, though (as Mark says, there is always vodka)
Socialism: takes away some of the aggression caused by object-desire
