MOSCOW - President Vladimir V. Putin has made it crystal clear that he has no love for Russia's mega-wealthy, and he has worked hard since his election in 2000 to limit their influence.
But thanks to the bargain-basement sale of state assets to Kremlin insiders in the 1990s, Russia's super-rich still control a huge slice of their nation's economy.
Forbes Magazine estimated this year that there are 17 Russian billionaires, based on public documents. Most likely there are others, living here and abroad, whose wealth is hidden in offshore companies and discreet banks.
Most of the high-profile tycoons, called oligarchs, still work out of high-rise offices in Moscow surrounded by platoons of security guards. But in the past few years, several have fled overseas under pressure from prosecutors and police.
