It is incorrect to compare Russia and other top countries, Russia is not a normal country, it is captured by a regime whose basis is systematic corruption and the removal of honest professionals from any business. It is very difficult for a talented child from a poor family in Russia to eventually become a professional player. But what happens when this country actually cares about hockey is something you saw in the 80s. This post will probably be deleted
Russia is no different than anyone else in this regard.
Sure there are outliers, but generally speaking no poor people play hockey anywhere.
