If you were rich you'd marry someone else rich. Divorces are financial ruin. Someone is going to lose a lot of money. You might as well marry someone who is also loaded so that money isn't an issue when you split up. Tiger Woods, Johnny Carson, Michael Jordan, and lots of other high profile individuals lost hundreds of millions to divorce.
Tom Brady had the right idea, marry a broad who has even more money and fame than you do, so if you divorce she won't ask for money and you know she isn't digging for gold or fame *cough* Beth *cough*.
