I have been back over my charts, and like the Mills chart, a greater percentage of goldigger types indeed had Jupiter in the 7th with Sagittarius on the 8th cusp. So, perhaps the 8th house ruler in 7th or 8th seems to represent that potential. "Sugar Daddy's" would seem to be Zeuss like or indeed have some kind of value to offer. One past relationship of mine, showed her Jupiter in Gemini on the 8th cusp close to the nodes. I had no monetary or assett value whatsoever. She did however thirst knowledge and many months of constant discussions seemed to be great value to her.
When I stopped giving her one of the things she seemed to value in me, her capricorn Moon in 2nd took over. She claimed that our relationship could continue as long as I put $100, 000 of assetts on the table. I said to her, "yes, well even if I did that, next you will be saying we can only have a relationship if I grow some hair back"
Gold digger is a derogetory phrase and perhaps one might best look at ones expectations in relationships, "what compatabilities we have in common" or "what I need in you to be able to continue being more me" There is a kind of dependancy or reliance involved and perhaps professional gold digging is more manipulative than accidentally incurring great wealth through relationships.
Mills has a very interesting chart if its accurate. Moon opp Venus tends to be relationships for the sake of relationship. She is a beautiful woman that is for sure, but nurturing? Perhaps Sir Paul thought all his pain would be released with her? It turns out they are both a nightmarish learning lesson for each other and its high time they did some learning. Spanking them!
