So, are Russians taught about socialism and communism?
I think more than 3/4 of people do not know these things. Maybe more.
Idea of "USSR crash as the result of congenital malformations of the planned economy" was very important keynote of the 90th during capitalization of Russia, so, most of people believe it.
There are few people who realize that modern developed countries are synthesis of planned and market economy, synthesis of socialism and capitalism.
