Anyway, on balance, I don't think Rand was too bad as a self-help thinker.
The sort-of-generalized premise that selfishness can help one attain his goals, and that this can benefit both the individual and society despite the egocentric focus, seems sound enough.
The issue so many have is that instead of writing self-help, she wrote fictional polemics, where she alone was able to mete out the good and the evil in her world, and she handled this with all the subtlety and restraint of Genghis Khan, making everyone who supported her fantasies godlike, and everyone who opposed them subhuman wretches out to destroy her people out of envy and hatred. Made for successful rah-rah storytelling, but has obvious crippling issues as a philosophical groundwork. She was nauseatingly solipsistic.
