Well, if she only got $100 million, I can see why she had to declare bankruptcy. You can't be expected to live on that.
She (and her next husband) made investments (in a winery and in some real estate developments) which flopped when the Big Recession hit. Such shit happens to many people (who once had assets enough "to live on"); there's no reason that it couldn't or shouldn't happen to women. If rich men are "allowed" to fail spectacularly, so do rich women. If a woman is to be faulted for squandering her considerable assets on bad investments, so do those men who make the same mistake.
But if she did get nearly a billion, then she WAS ALSO getting payments of well over a million a week on top of that. It just wasn't coming from the sap she married and divorced, it was being generated by the assets.
OK, now I see that you've used 'payment' in a wider sense I was thinking of. Of course no one offers yearly fixed 'payments' (interest) of 8.3%, certainly not over 18 years (with three intervening recessions).
Anyway, the bigger question here is why feminists don't focus on this particular inequality between the sexes. I thought that feminism was about equality, so I'm really confused now.
Maybe because men can score on divorce settlements, too:
Larry Fortensky got a million from Liz Taylor.
Kevin Federline got a million from Britney Spears.
Jim Threapleton got $4 million from Kate Winslet (half of their common property).
Parker Stevenson got $6 million out of her divorce from Kristie Alley.
Peter Andre got $9.6 million from model Katie Price. This was half of what they made during their marriage.
Rene Elizondo, Jr. reportedly got $10 million from Janet Jackson.
Cris Judd got $14 million from Jennifer Lopez after a 9 month marriage.
Harry Glassman got half of the community assets ($25 million) when he and Victoria Principal divorced.
Tom Arnold got $50 million from Roseanne Barr.
Guy Ritchie got $92 million from Madonna.
These settlements aren't in the hundred million dollars range (with the exception of the Ritchie-Madonna case), but the women involved aren't billionaires either (with the possible exception of Madonna). So if you're a man and apply yourself to the task at hand -- so to speak --, you can make half of her money (or at least a nice chunk of it), too.
