Taking Half in a divorce?

So heres my question... Im reading yahoo news and Michael Jordan and his wife is getting a divorce. She is about to get 100 million or something like that from him just cuz she was married to him.... Is that fair? Now I know some women will say yes because she had to put up with mens bs but... this is MJ we're talking about. He's rich and always was rich. She didn't have to lift a finger. All his money came from HIS talent, HIM playing basketball, HIM making endorsments, HIS name. I would understand if she had something to do with that, but she has absolutely NOTHING to do with that... wheres the fairness in that???
