How wealthy is Russia?

In general Russia is poor compared to U.S, Germany, Japan and other major countries but Moscow is the city with most billionaires in the world, that means that there's 1% group who has 80% of russia's wealth, this group of rich oil, steel, and gas magnates are thiefs, they just took the resources of russia after the fall of the soviet union and made the papers look like they bought it. And now they use cheap russian labor to dig out those resources to sell them to foreign countries while their own people live in poverty, thanks to Mr. Putin!
