In addition to being a fiction writer, Rand is also a "philosopher" (quotes because I use the term loosely). Her "philosophy" of objectivism is one of the key tenets of the so called Libertarian movement all of you 20-something-upper-middle-class WASPS subscribe to.
Which is exactly my point of contention with rand and her followers. There is no "free energy machine", nor would the world stop if all of the "Atlases" suddenly "go Gault". If all the business leaders and innovators suddenly left, there roles would be filled by other people.
Likewise, there will always be a capitalist class working for their own benefit. Even if taxes were increased another 3-5%, it is still many times more lucrative to be a CEO than a garbage man.
