I've learned through experience of playing different characters, some of whom were jerks, that when you play a character who is pretentious or obnoxious, in any way, it's important to knock them down a peg.
Of the billionaires I have known, money just brings out the basic traits in them. If they were jerks before they had money, they are simply jerks with a billion dollars.
I said that liberals think people who live in the middle of the country are a bunch of jerks, and obviously all liberals don't think that. But I will tell you what, an awful lot of liberal elites think that.
