"She's accustomed to the lifestyle." I had this argument with a few coworkers when there were rumors of Tiger Woods' settlement being in the range of 300 million.
It's like, realistically, even if you have two kids, and you raise them from birth to the age of 18, $1 million US dollars a year, per child, is more than enough to ensure that the kids are in the top 1% of people in the world in terms of lifestyle. Over 18 years, that's $36 million for two kids. Say you round up for inflation, you get to $70 or $100 million even.
Why is $300 million reasonable in any way, shape or form? What are you giving compensation for? It seems much more like a) an award for successfully marrying "up" an b) a penalty for breaking your marriage vows. I don't believe the judicial system has any business doing either.
