Question about gold diggers? What do you think?

Do you think that a woman who is with a man 10, 20, 30, or 40 or more years older than she is could actually love him and not be a gold digger, or are they all gold diggers? For argument's sake, lets say that the man is well-established and comfortable but not necessarily a multimillionaire like Hugh Hefner and the woman is at least 21 and self-supporting.
