Yet few novels have had an impact as enduring as Atlas Shrugged, a dystopian allegory in which captains of industry struggle against stifling regulations and an over-reaching government and one by one close down production, bringing the world economy to its knees. Rand's philosophy, which she called objectivism, tapped directly into the American ideals of freedom, hard work and individualism. In novels like Atlas Shrugged, and her non-fiction like The Virtues of Selfishness, Rand argued for the removal of any religious or political controls that hindered the pursuit of self-interest.
