She reads her selection of 47 writings of Alexandra Kollontai (occasionally interspersing explanatory comments), a Russian revolutionary author nearly a century ago. In these writings Kollontai, among other subjects, explains how even our emotional lives and social relations have been determined by societies with ruling classes (especially Episodes 8-15) after humans settled in agricultural communities. Kollontai writing nearly a hundred years ago even extrapolates into the future what these will look like in a classless socialist society. (Note: I encountered a few technical problems in this series.)
Unfortunately the Soviet Union, under constant attacks (invasions and trade embargoes) by the Western capitalist nations, soon came under the authoritarian control of Stalin after Lenin died from wounds in an assassination attempt in 1918. The socialist revolution degenerated under the rule of this dictator who surrounded himself with supporting bureaucrats which eventually became a self-serving ruling class. However, under Stalin's rule women were still better off than their Western counterparts as Ghodsee explains in another article entitled No Scrubs.
Also unfortunately, we as a species, and most others, are destined to become extinct due to the trashing of our environment by capitalist nations before a socialist society can even be realized.
