What shapes one's politcal view?

Is it upbringing?
Social/Economic standing?  (and does it change as you get richer/poorer?)
Personal values?
Education? (how, when, where, and by whom)
Propaganda and Memetics?


I'm inclined to believe that most people's political views are based on what they believe will benefit them the most personally.
