So let’s say you’re a rich celebrity. You decide to move all your money from US banks to the Caymans so you don’t have to pay taxes. Maybe you even change your citizenship to there. They happily take your money and store it in one of their underground sugar mines. Then what? Out of the goodness of their heart, they agree to be a target of governments trying to sue or pressure them into giving up the info on who has what stored?
I’m assuming that places such as these don’t have taxes so that’s why people move their money there. So why would they do that? Surely get they something.
