The billionaires who pass out the right-wing Kool-Aid are desperately trying to push the fantasy that they are going to act out Ayn Rand's novel, and leave us all to starve if we allow that Kenyan Socialist to raise their taxes by a couple of points.

They're really afraid that the middle class will realize they've been screwed and start wanting their country back.
Own a chain of mediocre restaurants that allow you to live in castle (literally) while you pay the help almost nothing? You might be paranoid about the peasants catching on that you aren't really entitled to do that. They are scared to death of Liberals because of the very meaning of the word. Liberal is short for Liberal Enlightenment, the idea that we all have a say in the society we live in. The idea that the rich and powerful aren't really the enlightened few who get all the rewards from our work because they are in charge.
