NHLers are largely and increasingly coming from rich kid backgrounds, as the sport becomes more expensive and demanding. But that's still far from being everybody.
"Kids who grew up in Russia in the 1990s" should encompass most of the NHLers who grew up in poverty. Russia was in a state of economic collapse in the 90s and many people were on the edge of survival. Alcoholism was at epidemic levels, you can look through rosters of Soviet teams from the 1980s and see how many of the players died in the 1990s - either from alcohol directly or from violence or car crashes. Half of some teams died young from various causes! Deaths from gang violence would have succeeded anything comparable in any part of the United States. Sport was an entirely public investment prior to that point and suddenly all public support disappeared. There were many rinks closed down.
So that makes it all the more stunning that a kid like Panarin was able to make it. Artemi wore shoes inside of his grandfather's skates, his grandmother sewed his gloves from old leather, and they taped together discarded equipment that they found. He was still far from the rink and had to travel on public transport alone as a boy to get to Chelyabinsk, and he was supposedly often shaken down on the way.
What are the stories with Datsyuk and Kuznetsov?
