So commies don't want to ruin civilization?
The commies had already ruined civilization so badly by the time that John Galt et. al. came on the scene that the current one was unrecoverable. The members of Galt's Gulch were destroying the old one to create a new one. The old one was inevitably going to destroy itself no matter what they did. The only question was "Should people hang on in a futile effort to preserve it, or take the best of the old and reboot the system?"
Her main thrust in the book was about the evils of communism.
"So commies don't want to ruin civilization?"
You are having a logical disconnect here, it does not matter to this subject, if the commies want to ruin civilization or not. This book was about value for value, not something for nothing(communism)...worked by your ability, paid by your need.
Maybe you should reread this book? I still don't think you've read it, but that's just based on your comments here, and what do I know...
