I believe this is true when someone has exhausted all of the distractions in life that their money may be able to provide, and find themselves with, still, an empty space.
Many find themselves in relationships that are of the world. Not of spirit. They attract exactly what it is that they project into the world. Do wealthy men who hook up with pretty woman that just want "things" such as a new hand bag or a new pair of shoes do so because they don't believe they deserve to love and be loved in the deepest most intimate way? I'm not sure of the answer to that question.
What I do think however, is that there are plenty of people who have come to the end of themselves and their money. They have a true heart felt desire to share a union with one that makes them complete, joyful and grateful for the love they give and receive. Truly a bond that would sustain with or without the cash... to put it bluntly.
What I think may complicate things for many people of means, is that it can take a long time, even a lifetime for some, to have completed the cycle of life experiences necessary to live in spirit rather than ego.
