As previous poster said:
"Unfortunately, it did not last "annually," as his wife found out after seven months and put the "squeeze" on him. "Dissapation of marital assets replete with paper trail," is not for the faint of heart."
As one financially well off, I think that marriage and abuse of divorce laws produce the biggest gold diggers in the world. There is no bigger gold digger than a married woman. Better for the rich to avoid monogamy or marriage at all costs. I would rather go for a sugar babe with known costs than give a lien on my wealth to a wife with unknown costs and potentially wealth damaging divorce actions.
Also marriage these days don't last long anyway with huge penalties for the man to leave it, so better to go in for arrangements.
