Ayn Rand was right about a lot when it came to people.
That's why I like her work, she starts from fundamentals. Christians say everyone is a sinner and needs Christ. Ayn Rand agreed - and then observed that most people do NOT receive Christ in their hearts. So she simply asked, okay, how would such people, who refuse Christ, act? What WOULD govern their behavior? How would they justify it? What would they actually do?
Simple, but brilliant.
I'm finding it uncanny that her novels make it seem like she traveled into the future to get her material from current Demoncratic politicians. She almost verbatim nailed it - over 50 years ago!
