What Provokes Angst?: Do Genetics cause Bitterness, Or Did George Carlin Just Get Made Fun Of a Lot For Being Ugly?

I watch a George Carlin stand-up routine at night before I fall asleep, and most of his humor centers around hatred towards a clandestine group of businessman who "own" people.  Abraham Lincoln (I think) abolished slavery.  In America, one person can't literally own another person.  For some reason, George Carlin had a lot of built up angst.
