Vladimir Putin is the wealthiest man on the planet, for sure. But this is different to the wealth of a Bill Gates or a Warren Buffett, a Carlos Slim or a Sergey Brin. They stay wealthy whether it is Barack Obama or Donald Trump in power. Putin's wealth depends on him staying in power. It is all about controlling the budget, the hard currency reserves and keeping under his thumb the oligarchs who cannot move their money without his permission. It is something close to a trillion dollars that he can control and move.
