In the 1950s, students started gathering in Paris. They were reading Karl Marx. They were forming book clubs. They were trying to come up with a better version of society. One that moved away from the division of labor. One that moved away from the capitalism in the big cities that they so despised. ... One of those students would change his name to Pol Pot. He and his colleagues formed a new political party, a takeover in Cambodia. They called themsevles the Khmer Rouge. ... Under Pol Pot and the Khmer Rouge, one out of four people in that country died in less than four years.
