I think it is pretty ridiculous that these people never have a career and expect to be kept at this same ridiculously lavish lifestyle forever, despite the divorce. I mean, it shouldn't be like winning the lottery. I think that the wealthier person maybe should have to help them get back on their feet for some period of time, if they asked the gal to quit working. Then, she should support herself. Of course, the non-custodial parent should also pay reasonable child support.
By the way, I have seen cases where it is the men who live off the wealthy women after the divorce.
