Yes, you may be correct. The authors phylosophy comes across as very hard and selfish. It is a Hard Right view of capitolism. The authors basic principle is that the profit of a man’s labor belongs to him alone. The book is very anti union / socialist / communist.
The author also detests any form of charity. That comes through particularly clear in the Fountainhead. Objectivism is not a Christian philosophy; its a philosophy of “I’ll get mine and screw everybody else. Somehow this leads to utopia.”
I haven’t read Fountainhead, but I don’t doubt that you are right. Rand does seem to have been a very hard woman. But if her language were softened a bit … well, if everyone worked ( honestly and rightously) twords their own best intrests, you might get closer to utopia than other systems might. I don’t know her reason for her dislike of charity. I don’t like it either, that is, who wants to be needy? I am not against providing charity though. I do agree with her on the values of hard, honest work, competition, personal excellence, and profits to the profitable. Her lack of any religous philosophy does leave her final conclusions wanting. That " God shaped hole" that is in everyone is never satisfied in her characters, nor is it mentioned. The lack of any spirituality keeps her characters swimming in the shallow end of the pool.
They’re set in contemporary times and have a wonderful mixture of drama, mystery, danger, and romance. Strong Catholic themes, but not preachy.
