Don't mistake me...Tiger is an attractive man. But even with his good looks, does he really think she would have married him if he made $30K a year? She may have worked as a nanny, but she was also a swimsuit model. She was not the "average Becky" and had no plans to marry/sell herself cheap. He knew this, and that explains the prenup. I don't have any empathy for trophy wives or the men who marry them.
In all honesty, this is not a "black man marries white woman" problem. The problem is not the color of the wife but the character of the man. Think of all the white famous people who cheat. Think of all the famous black people who cheat, even when they have black spouses. And think of all the couples you know out in the real world. Also, women cheat too!
