Russia's population has been [ decreasing for over 20 years ](
http://www.nybooks.com/blogs/nyrblog/2014/sep/02/dying-russians/ ) ; Russians die younger and have few children. One author says this is because Russian society has learned to give up hope. If that is true — I don't take it as certain — then it probably relates to the cruel capitalism that took over Russia in 1991. The same thing might happen in the US if the plutocrats cement their power.
