I'm not sure that anything in Ayn Rand's novels actually corresponds to the realities of corporate capitalism. I'll take one illustrative example: the discovery of Rearden Metal. In
Atlas Shrugged, Rearden Metal is depicted as the product of the lone genius of Hank Rearden, who defied his own corporate scientists and a made a metal that everyone else considered impossible. At the time, Hank Rearden was not a lone inventor working in his garage. He was already a plutocrat, with multiple millions to his name, and a large corporation backing him.
Can you actually think of a case in the real world where that's happened? Where the CEO of a multi-billion dollar corporation has personally made a breakthrough discovery in his or her field? Of course not. Billion+ dollar companies are crazy complex machines, and our hypothetical CEO has far too much to be doing to be merely mucking around in the lab like a lowly research scientist. He (and I use the masculine deliberately) has a corporation to run. He has decisions to make!
No, the closest thing I can think of to Hank Rearden is Tony Stark or Bruce Wayne. Genius CEOs of multi-billion dollar corporations who, by virtue of their sheer brilliance come up with discoveries that all their trained underlings miss, despite having far less time to devote to the topic at hand. And, for that reason, I find Ayn Rand's scenarios to be deeply irrelevant. Her characters, plot, and morality are more suited to comic books than novels. There is no ambivalence, no ambiguity in any of her characters or her situations, and her books turn into thousand page morality plays that one reads without gaining any insight into how one should actually behave in the real world.
To say that a living person corresponds to a character in an Ayn Rand novel is akin to saying that a living oak tree corresponds to a page in a notebook. You can argue that there are commonalities. But the commonalities between living wood and dead paper do more to obscure than clarify. It is the same with comparisons to Ayn Rand characters. At this point, I'm ready to just throw out Ayn Rand analogies altogether in my rhetoric, for they seem to add more heat to the discussion than light.
