Her chief protagonist, John Galt, is an uncompromising superman. He is the proverbial Atlas who holds the world on his shoulders. He has invented a fantastic motor, yet is so frustrated with state authority that he withdraws his talents – hence the title, "Atlas Shrugged" – and spends the next dozen years working as a manual laborer for Taggart International.
Mr. Galt somehow succeeds in getting the world's top capitalists to go on strike and, in many cases, strike back at an increasingly oppressive collectivist government. Rand's plot violates a key tenet of business existence, which is to constantly work within the system to find ways to make money. Real-world entrepreneurs are compromisers and dealmakers, not true believers. They wouldn't give a hoot for Galt.
Rand, of course, knows this. And that's OK, because "Atlas Shrugged" is about philosophy, not business. In her world, there are two kinds of people: those who serve and satisfy themselves only and those who believe that they should strive to serve and satisfy others. She calls the latter "altruists."
Rand is truly revolutionary because she makes the first serious attempt to protest against altruism. She rejects the heart over the mind and faith beyond reason. Indeed, she denies the existence of any god or higher being, or any other authority over one's own mind. For her, the highest form of happiness is fulfilling one's own dreams, not someone else's – or the public's.
Galt crystallizes the Randian motto: "I swear by my life and my love of it that I will never live for the sake of another man nor ask another man to live for mine." No sacrifice, no altruism, no feelings, just pure egotistical selfishness, which Rand declares to be supreme logic and reason.
