thats complete bullshit.
counterexamples... the soviet block.....poland ukraine, belorus, lithuania, estonia, czechoslovakia, etc..etc..
and then again each in tur again, for decades, as they gradually rose out of the mold and fetid decay of socialism.
some still struggling... take Ukraine as example.. and Russia...a backwoods has ben power of aged monolith construct and systems....
futherm many of the greatest barbarisms in history are encompassed with the above, too
Russia: from gaslight and a majority illiterate to pioneering space exploration and building the first nuclear power plants in a couple generations. Typhus eradicated. No longer the site of regular large-scale pogroms against Jews. Abortion legalized (except for a period when reversed under Stalin). Tremendous increase in levels of education and of women's education in particular.
Poland: no longer the site of Nazi death camps and persecution of Ukrainians, or ruled by an SS general with the aid of the Gestapo. Jews no longer massacred. Abortion legalized.
Ukraine: no longer the site of Nazi and fascist racial massacres, large-scale pogroms against Jews, Cossacks terrorizing peasant communities and cities. Abortion generally legalized. Went from a largely rural, agricultural community to a largely urban, industrialized community. Tremendous increase in levels of education and of women's education in particular.
Lithuania: never became socialist in terms of economy. Annexed for reasons of military necessity and treated as a capitalist colony of the USSR for the benefit of an exploitative Russia. But if you want to say they
Estonia: same as Lithuania.
Czechoslovakia: no longer under Nazi control. No more deportations to death camps. Abortion legalized. Antigay discrimination banned. First country to eradicate polio.
