And this is why you build a super yatch, with missiles and submarines and a crew of 70 ex-SAS soldiers, when it dawns on you that your billions in wealth were not the result of real hard work or ingenuity but the result of shady deals, loans for shares and political favours that enabled you to buy a 50% controlling stake in the giant Russian oil company Sibneft for $50 million- way under the market value at the time and in hindsight under valued not in the tens of millions but billions.

Or just to show off how rich you are!
