I once had a conversation about a similar topic and the woman with whom I was talking said it wasn't about the money per se, for her it was about POWER

she was attracted to (in her words)"the magnetism that comes from a guy who is running the room. Oftentimes," she said, "from her experience the guy who is controlling the environment, in regards to people's responses to him, is often the one with the most fattest pockets." As such, she developed a proclivity for guys with money

so, perhaps the attraction guys "believe in" isn't from the money but what it brings
