It is quite hard for a compassionate individual who care about resources, or people to see the persuasive power of Ann Rand. To those who care, she seems rather cold and stupid.
If however you are a narcissist, and look to yourself first, suddenly she seems to make sense. If you really really want to be good, but don't want to put in the effort and sacrifice that it takes to be a good person, suddenly her appeal takes off. How wonderful it is to have greed and selfishness as virtues. These two factors are the easier ones to understand but there is a third one that grabs the young college republican type strongly. Ann Rand answers questions the way that they need them answered.
First some background,
This research supports the theory that conservatives are predisposed to think in black and white terms;

http://www.msnbc.msn.com/id/15534009/If you combine the thoughts and imagine a child who is miserable whenever there is not a clear answer or solution it becomes clearer. This child is conditioned by his own brain to need clear definite answers. Assuming he is of reasonable intellect, he will become quite good at rationalizing and will likely develop a split between his ethics and what everyone elses ethics should be.
For example, abortion. There is no ethical stand that can be taken here. Anyone rational can shoot holes in any stance that can be taken on the subject. The individual who needs a black and white answer will be drawn to the moral high ground for others, and the convenient choice for themselves. Neither of these choices are really driven by ethical ramifications.
This mindset is very much the Ann Rand mindset. Her bizarre philosophy will likely give them tools to resolve some of their conflicts. They are conditioned from birth to need black and white answers, in a world filled with wondrous colors. In a very real sense, these folk are retarded. I pity them, but I don't want them to make decisions for the rest of us.
