The crucial point here is that no tax evasion or undeclared Swiss bank account is involved (as far as we know). Even a person of the most refined taste and elegance cannot easily spend 500 million euros a year on current expenses. It is generally enough to take a few million a year in dividends (or some other type of payout) while leaving the remainder of the return on one’s capital to accumulate in a family trust or other ad hoc legal entity created for the sole purpose of managing a fortune of this magnitude, just as university endowments are managed.
