I'll weigh in despite the fact I'll undoubtedly get flamed for saying this, but the Randian view of the world is naive and borderline childish. It was ok for the time, I guess, but modern behavioral economic models show that individualist strategies actually lead to suboptimal outcomes.
As an example, consider a game between two players. One player is given money and offers the other a deal to split the money. The second player can either take the deal and keep the offer, or he can reject the deal and both players get nothing. It is in the first player's best interest to lowball the other player, maximizing his share, because it is also in the second players best interest to take any offer, because even a lowball offer is better than none and means money he didn't have before.
That is bad strategy for both though. Long term, it is better for the second player to reject offers because that puts pressure on the first player to offer higher. It is in the first player's interest to make higher offers at the outset and avoid having offers rejected. Despite being the one with the money, the first player can't dictate the game. He and the second player must come into agreement on fairness for either to benefit.
Rand's characters and thoughts are oblivious to this. The Dagnys and Reardens have this opinion, "My business, my money, **** all you little people wanting s bigger pierce of the pie." The problem is that they're the first player and making what the second player, everyone else, thinks is raw deal. Government intervention and unions are simply their way of rejecting it.
Now, alternatively, you could view everyone else as a second player asking for more than a fair offer and Rand's heroes refusing to make them anything else, and that might be valid.
However, that is also contrary to Rand's own ideas on objectivism, as if the world could be reasoned into black and white. Reality is inherently a matter of perception and estimation, and it is decidedly not objective. Certainly, some things are objective, but the human experience is not one of them. You cannot have a world that can boiled down to objective absolutes and still have disagreements that can be argued both ways.
Personally, I think the situation is the former. Rand's characters are self-righteous and self-important. They're of the mind that they built their empires and deserve everything while everyone else should take whatever they're offered. So does Rand. I tend to disagree, as their empires wild not exist without their employees. As profits grow and the business makes more money, the disparity between owner and employee compensation grows as well. Now, it certainly shouldn't be equal as the owner has put forth effort and taken risk to bring the company into being, but the employees are also key players as well because without them, collectively, the business makes $0 and the owner gets nothing. In the game, this is the first player getting a larger pot of money, but still giving the second player the same deal. Eventually, the second player reaches a point where they begin rejecting the deal on principle because of the new disparity. If Rand's characters took a more cooperative approach, they'd end up doing better in the long run.
In the end, the non is nothing more than a pontificating ideologue's wet dream. It's full of idealism on how the world should work according to Rand and her followers, but it diverges from and ignores how the world actually works.
