Switzerland, WW2. There is safety in holding EVERYONE's money. Because the moment you try it, you enrage many, many, many people who have things that go boom. You can fuck with someone's politics, their car or even their wife. But once you fuck with someone's money, it's a whole new ball game.
> I don't understand how this is even legal at all
Bank fees are higher. The different "islands" that do this, really don't have a choice. WTF else are they going to do as income generation? There's only so many happy endings you can give in a day spa. It's also easier to "invest" and hide the money in tourist based enterprises on said islands. It totally makes sense to hire an interior designer for $10k an hour.
>how can they trust so few people to hide so much money
Because people don't like getting into car accidents. When you're "trusted" with something on that level, suddenly people make sure you either don't have or do have car accidents that magically attract stray bullets.
>I mean apparently there is a long list of why it's risky, and I don't understand how this is even legal at all.
Homie, avocado farmers in Mexico get kidnapped and executed because avocados are cash crops. Shit, look up "avocado stolen" or even "avocado semitruck stolen". No such thing as making bank and not having risk. Some of those truck drivers in the USA get killed. If you're going to get targeted for making money, might as well go all out.
