Barry Shain's The Myth of American Individualism is a good historical debunking of Randian wishful thinking. Most of her thought is refuted by experience, wisdom, and humility.
Let me guess. When you read Ayn Rand (and I give you the benefit of the doubt) your traumatization at the hands of The Church prevented you from being able to understand what individualism means. Dumb-Ox indeed.
Then tell us what the US of A is about. Is it about the law of the jungle or is it about privileges granted to citizens by the state?
