The real resource they have is their money. Other than that it's all stuff they buy with their money to be able to have assets to hold their wealth and I don't mean just mansions I mean paintings, jelwery, antique and vintage furniture of value. Clothing that needs to be stored a certain ways, wines and collectable foods, historical documents of value, historical artifacts in general......

Things that we would never even think of is what they hold their wealth in which is why they use trusts and company holdings and offshore bank accounts so they're not holding their full assets and net worth.

Like that one painting that they all say is worth 20 mil, is that 20 mil that's not in their bank account but is always obtainable through auction. It makes you less of a target if your wealth is spread and diversified.
