It's really a misconception. She is attacking the popular saying "The love of money is the root of all evil". She is attacking it as a blanket statement (in a fictional way, of course, in Atlas shrugged - >>>just to confirm that we DO relaize what Orion is saying<<<). It is not the actual scripture she is attacking in actuality (though she may think she is) but a misunderstood saying based on that scripture taken out of context.
The real meaning behind the scripture is not even addressed. To me it is like someone attacking the catch phrase "God helps those who help themselves" or something like that. That is why I suggest that trying to refute the catch-phrase "love of money is the root of all evil" is an excercise in vanity and futility - it is a "straw man". You know what I mean?
