The fundamental contradiction in Rand
There is a contradiction in the position of Ayn Rand. On the one hand, she's arguing for self-reliance. On the other, she's promoting a victim mentality. That tends towards refusing responsibility for your own choices.
Let me give an example of this. I have a friend who is an admirer of Rand. He thinks of himself as an individualist swimming against the tide of our evil society. But he's never really taken responsibility for the choices he made. While he's intelligent, he never got his act together to finish his college degree or determine what kind of job he could do. So now he claims that his failed life is the fault of immigrants and corrupt government. If we had no immigration in America, he would've had a job and a decent life. He yearns for an Adolf Hitler to bring justice to the country. He even fantasizes that he would be one of Hitler's advisors.
Now, you'd think that would be a pretty untenable contradiction. He'd look himself in the mirror and think, "I screwed up." But once you think of yourself as a victim, you can justify almost anything. Even murder.
The contradiction in Rand's own life wasn't quite as bad because she did take chances and stretch herself to do creative work. She "found her calling." But still there is an overwhelming sense in her thought of victimization. She was a victim of the Russian Revolution, but all her life she seems to have imagined the government was going to come and seize her hard-earned wealth. There was never any danger of that in America.
