Socialism's brutal history had been kept hidden by the countries that embraced it for countless decades, until evidence of the autrocities began to emerge in the latter half of the 20th century. The genocide that defined Socialism in the USSR had been the model for every Socialist government there after. And it wasn't the accidents of dictators, but the intentional actions of intellectuals and some of the most highly educated people the world had ever known. Khieu Samphan was a Cambodian intellectual who developed a variation of Marxist economic theory as his doctoral thesis, while studying at the prestigious, Sorbonne University in Paris. After rising in within the Socialist revolutionary party, Khmer Rouge, in Cambodia, Samphan reorganized the countries entire population to fit the economic model he developed in an effort to achieve economic equality. The results are depicted in the 1984 movie The Killing Fields. Millions were exterminated and Samphan was convicted of genocide. Socialism is always a coordinated effort between countless numbers of ideologically driven, highly educated people. Sampham dismissed the narrative that Socialism's bloody history is the result of the the actions of a few dictators.
