"The characters are thin shells used to promote Rand's thinking and in no way reflect reality."

Well, whose thinking do you think they should have promoted, exactly? And why do characters in a novel necessarily need to exactly reflect reality? I haven't run into any elves, dwarves, or immortal wizards, but that didn't stop me from enjoying Tolkien.

"The idea that unbridled self interest leads to the greatest good guided Greenspan's monetary policy and got us into this mess."

Really? How do artificially low interest rates translate into unbridled self interest?

1. If a novel is intended to be realistic fiction, it should reflect reality, not the author's philosophical agenda. (My opinion, but I think this is the only way serious art reveals truth. Imagine if Marx had written a novel.) This is distinct from fantasy. I'm a Tolkien fan too, but I don't think anyone would turn to LOTR for economic guidance.

2. Artificially low interest rates reflect Greenspan's belief that given enough liquidity, markets will be self correcting. He thought banks were in the best position to protect themselves from risk because they bear the greatest consequences of failure. (He has since admitted the failure of this belief.) Clearly they were not, as the low interest rates lead to further inflation of the credit bubble.

You could say the same thing about every character ever written. They're all extensions of the author. Even a character as complex as, say, Stephen Dedalus, is in the end a product entirely of his creator's mind. One of the catches of reading fiction is that you always need to remember that they are the product of a single mind.

> There is certainly a lot to be said for enlightened self interest and personal freedom, but the absolutism of objectivism is just as wrong as communism.

But which concept is better? When you subscribe to an idea you do it for the practical idea of it. Communism says that you should put everybody in front of you, and do what everybody else thinks you should. (Or rather, subjectivism does, since that's the true opposite of Objectivism; Communism rather states that the community is more important than the individual, which is closer to subjectivism.) Objectivism says that you should rely on yourself to do what's right. The one is much healthier mentally, and that's a good sign.
