Yes, I disagree with her philosophy. Rand believed that a person had no further moral duty than to pursue their own happiness, and that you are solely responsible for your success or failure. If you succeed, you should be applauded and be given the deference to do what you want. Those who point out that the government, by and for the people, provides for the schools that educate the workers, the roads that are use to deliver products, the police who keep the country safe, etc., are parasites and moochers for wanting the wealthy to acknowledge this and contribute to paying for the services the government provides. The same goes for unions who want recognition and fair wages for the workers.

If you reject her philosophy, it's very hard to identify with the characters she positions as the good guys. And why else do you read fiction if not so that you can root for the good guys?
