Marrying for money is probably a bad idea under any circumstances.but is absolutely nuts if you are already rich.

The wise know that if you marry for money ,you will earn every penny for it.

So if you are already rich ,why on earth would you want to work that hard! It is easier to marry for love and make the money later.It is what Warren did with his wife ,Susie- then found love and then they went out to make a fortune.Besides, the couple that makes money together is often the couple that stays together.And if they don’t stay together ,at least they have a ton of money to fight over.[Warren is silent on the wisdom of divorce].
