I remember this one part of the documentary Born Rich where one of the recently-turned-18 kids said that when you're born stupidly rich in the US, getting sued over something -- anything -- is basically a right a passage. He basically said it's not a matter of if you'll get sued, just when you'll get sued.

Given how litigious the US is, if I were super rich I could not imagine keeping a significant portion of my assets in the country. If you have a lot of money it makes a lot of sense to not only diversify your investments but your jurisdictional exposure as well.

If you know the lawsuits are going to take forever (time) and cost a bunch (money), not having many assets in the US makes it easy to accept a default judgement, declare bankruptcy and write off the loss entirely without ever paying any lawyers a cent.

In this case, the people being sued seem like they totally deserve a lawsuit, but that doesn't change the fact that it is naive to not diversify jurisdictionally.
