You didn't put much care in learning anything about communism either despite criticizing it
Even if we ignore the fact Marxist-Leninism (which is the socialist ideology you associate all those "shitholes" with) isn't the only form of communism that can be implemented and is different to other left-wing ideologies as liberalism is to conservatism, are you aware that Marxism-Leninism was implemented in countries that were shitholes to
begin with because it was an attractive ideology for economically struggling countries?
Russia was primarily agrarian and far behind the developed western states during the time of the Russian Revolution and was heavily industrialized by the time communism fell.
