the guy is a billionare. At an annual ROI of just 2% on just one billion (he had several billion), that would work out to about $1.6 million a month, or close to $56k per day. I can't imagine being able to spend that much every day. I wouldn't even be able to enjoy myself because I would be spending all my time trying to spend money.
Like I said, whatever silliness is permitted by law is a totally different matter, and isn't relevant to a debate about what she should get from an ethical perspective, which has been my focus.
I'm not exactly sympathetic to a big oil tycoon, you poke her you pay her, that's how it works from the trailer park on up when marriages go south.
