Allow me a somewhat different perspective...These very rich men have the natural desire to procreate, to have kids..I mena, they want/need someone to leave the $$$ to..but they are still bound enough by tradional and values NOT to have kids out of wedlock....so, ergo, they get married, have kids, get divorced, and repeat the process ad nauseum. The brood mare, er, wife of the moment, is perfectly willing to go along with the arrangement, because the kid guarantees her financial sercueity for life..
I have to say, what I found a bit sad about this article, as per the paragraph mentioned in my post #1, is that today, the average couple feels that until they have enough money to make, they have to keep postphoning marriage. I also think this is a big result of the Women's Movement in the 1970's, when many girls were taught: DO NOT MARRY UNLESS YOU CAN AFFORD TO SUPPORT YOURSELF AFTER DIVORCE. Girls were not taught to look for the guy wtiih $20 million in that era. And, so, being unable to then make it financially, a lot of women never married. I think I have read there are more unmarried, single, never married women today in the US than at any time in history. And, it's not because they are all unattractive. It's because they took to heart this advice of the Women's Movement and waited, and waited, and then realized too late: they couldn't make it financially. It's very sad. I think this is why white women have the lowest reproduction rate, something like 1.2 kids in this country.
But, the Ellen Barkins of the world maybe had the right idea: go find the guy willing to hand over $20 million to you, up front-- and don't worry about anything else!
